Immortality | RuneScape Wiki | FANDOM powered by Wikia

Posted: October 15, 2018 at 4:41 am

Immortality is an ultimate Defence ability that requires a shield to use. When activated, melee, magic, ranged, and soft typeless damage the user receives is reduced by 25% for 30 seconds. If the user dies while the ability is in effect, they are returned to life, immediately cancelling Immortality. Immortality has a 30 second timer on the Buffs and debuffs bar.

When the user dies, an ethereal, blue hand appears and grabs the user, preventing them from falling down, immediately healing them for 40% of their maximum life points. While this animation is playing, the user becomes immune to all damage, similar to the effect of a short-lasting Barricade.

Upon being revived, the player receives the message “In a heroic stand you gain a second wind.”

If a player wears a sign of life or sign of death or their variants while Immortality is active and they die, Immortality is consumed instead of the sign or portent.

Several bosses can bypass Immortality’s effects; Vorago’s push mechanic, Telos’ instant kill anima bomb in encounters of 1000%+ enrage, Nex: Angel of Death’s elemental instant kill attack and losing Solak during phase 4 of the fight.

In PvP, Immortality removes the Teleport Block spell upon resurrecting the player.

100 Ways to Live to 100 | Best Life

Posted: October 13, 2018 at 8:47 am

So you say that longevity doesnt run in your family? Good news: You can change that. Turns out, your genes only have a 10 percent influence on how long youll live, and experts say that the choices you make throughout your life are much more important. At the beginning of the 20th century, the average lifespan was 31 years; today, its almost triple that, thanks to the cumulative effect of many, mostly minor, life tweaks that science has determined to have a real effect. The sooner you start applying these tips, the sooner you can start thinking about what youll be doing 50 years from now. What are you waiting for? (And while youre at it, check out these 40 Best Things to Do in Your 40s!)

There are a lot of mean old men, but are there a lot of mean very old men? Probably not, a 2012 study on aging suggests. Researchers from the Albert Einstein College of Medicine at Yeshiva University found a correlation between optimism and longer lifespans. A positive attitude toward life can be the difference between checking out early and being the last one at the party. For inspiration, try these 25 Ways to Be Happier Now.

Its well-established that yoga is relaxing, but have you ever thought about the cumulative effects of lower blood pressure, less stress, a healthy weight, less anxiety, and better breathing? Well, you should: Its a longer life.

Among those 65 and older, one out of five falls causes a serious injury like a broken bone, according to the Centers for Disease Control and Prevention. Though youve likely heard that sipping milk can help keep your bones strong and healthy, so can grapefruit juice, say Texas A&M University researchers. Studies show that the juice can improve bone density and slow the rate of bone loss. Juice a fresh grapefruit or eat one whole to reap the benefits. And be sure to fill your kitchen with more of the25 Foods to Keep You Young Forever.

Believe it or not, studies show that sleeping naked can slow the aging process. How? As we sleep, our bodies cool slightly, causing reparative growth hormones to be released. If youre too warm, you get fewer of those hormones. Plus, being cooler reduces the bodys level of cortisol, the stress hormone that can lead to overeating, diabetes and disease-causing inflammation.

Remember the 2012 study that found an optimistic outlook can extend lifespan? It found that a love of laughter can too. The 243 centenarians that researchers studied considered laughter to be important part of life. For a quick pick-you-up, try one of these 10 Drug-Free Ways to Fight Depression.

In their book The Longevity Project, authors Howard S. Friedman and Leslie R. Martin wrote that being conscientious was one of the best predictors of a long life. They posited that people who are diligent and responsible may be more likely to adopt healthy behaviors, may be less prone to disease and may find more success in relationships and in the workplace.

A study published in the journal JAMA Internal Medicine found that vegetarians have a 12 percent lower risk of premature death than meat eaters.

According to a study published in the journal Rejuvenation Research, people who practiced intermittent fastingeating for six days and fasting for oneshowed an increase in a longevity-boosting gene called SIRT 3 after 10 weeks. And before you ask: The participants didnt follow a particularly healthy diet. Both feast and fast diets included things like Oreos, cake, and bagels with cream cheese.

This one really is a no-brainer. But if you insist on seeing a study that shows smoking cigarettes is like playing Russian Roulette, here you are: Research published in the journal The Lancet followed 1.3 million people between 1996 and 2001. The study showed that giving up cigarettes helped subjects live 10 years longer than if theyd continued smoking.

According to a study published in the Journal of Personality and Social Psychology, adults who developed positive attitudes about getting older lived more than seven years longer than those who had negative feelings about it. Thats just one of the 40 Things to Do in Your 40s.

Want another reason to join the standing-desk craze? Sitting for less than three hours a day could add two years to your life, according to a theoretical analysis of existing data published in BMJ Open.

For decades, Japan has had the worlds longest life expectancy. But The Lancet suggests that may soon be outpaced by Spain, Italy, and Australia. But you dont have to move far away: Men in Canada live a full four years longer, on average, than their American counterparts.

According to research from The University of Queensland, Australia, every hour of TV you watch after age 25 cuts your lifespan by about 22 minutes. Researchers also found that people who spent an average of six hours a day watching TV died nearly five years earlier than people who didnt watch any TV at all.

A 65-year-old Hawaiian will live another 16.2 years, on average. Thats compared to another 10.6 years in Mississippi, the state with the lowest longevity rankings, according to recent data from the Centers for Disease Control and Prevention. Also, Hawaii is one of our picks for the Best Exotic Vacations in the World.

Although time spent watching the boob tube is associated with shorter lifespans, researchers who followed the news-gathering habits of more than 1,100 Italian adults found that people who had the most exposure to media were also the healthiest eaters. (Healthy eating, of course, is strongly linked with staying above ground longer.)

A study published in BioMed Centra showed that people who eat nuts have a 39 percent lower risk of early death than people who dontand walnut eaters, in particular, have a 45 percent lower risk of dying early. Walnuts, for the record, are just one of the 25 Foods to Keep You Young Forever.

It could cause you to tap out. A study published in Public Health Nutrition in 2012 found that people who cook at home up to five times a week were 47 percent more likely to still be alive 10 years later than those who didnt.

If youre going to take advice about how to stay alive, who better to consult than the worlds oldest living dude? Carmelo Flores Laura, a notable centenarian, told he owes his longevity to regular exercise. I walk a lot, thats all, Flores told the Associated Press. Jump-start your way to a fit new you with The Worlds Fastest Full-Body Workout.

A 2011 study from the University of Colorado School of Medicine found that the 20 U.S. counties with the highest life expectancy had an average altitude of 5,967 feet above sea level. That added 1.2 to 3.6 years to a mans life, lowering the risk of death from heart disease.

According to a Duke University Medical Center study, baby boomers who remain hitched are less likely to die early than their single peers. The findings were based on surveying 4,800 people born in the 1940s.

Youre only as old as the person you feel. Its supposed to be a joke, but there may just be some truth to it. Especially if you listen to 100-year-old Daisy Dunnett, who says she owes her longevity to having a younger husband. I really think I would be dead if it was not for him, she says. If youre elderly and on your own, its easy to give up and not feed yourself properly.

In a study of 1,700 married adults, researchers from Brigham Young University found that that the more arguing there was in the relationship, the worse the adults health.

The authors of The Longevity Project found that women who get divorced, often leaving a bad marriage, tend to thrive, as do single and widowed women. Why? Women were able to rely on other friends, whereas many men depended on their wives for their social networks and so were devastated when they lost these ties, one of the researchers said.

Youve got more than cavities to worry about if you dont brush and floss as often as your dentist recommends. Poor oral hygiene has been associated with shortened life expectancy. Maintaining a healthy mouth can lower risks for heart disease, dementia and stroke. So invest in a really good electric toothbrush.

Because a cup of joe is high in antioxidants, it can actually lower your risk for diabetes, liver damage, several cancers and depression. For that reason, its one of these 20 Amazing Healing Foods!

A long-term study published in the journal Mayo Clinic Proceedings found that those who drank an average of more than four cups of coffee a day were at a 21 percent higher risk for death than those who consumed less that that amount.

According to a Harvard University study published in 2008, people who stay in school for at least 12 years have more years of life ahead than those who dont complete high school. The research involved analysis of data from the National Longitudinal Mortality Study. A 2012 report from the CDCs National Center for Health Statistics went even further, finding that those who earned a bachelors degree lived nine years longer than those who only completed high school.

Research from the University of Waterloo showed an association between attractiveness and longevity. Researchers asked people to rate the attractiveness of 17-year-olds from pictures taken of them in the 1920s. Those who scored higher in attractiveness lived longerto 76, on averagethan their less-attractive counterparts (who lived on average to 69). For more ways on looking your best, be sure to check out these 10 Ways to Look 10 Years Younger.

Research shows that urbanites tend to live longer and healthier than their country-mouse counterparts. Its thought thats because of higher rates of cigarette use, obesity, and chronic health conditions (such as diabetes and hypertension) among people who live in the hinterlands.

A study showed that male Holocaust survivors lived longer than men of the same age group who immigrated to Israel before Nazi rule. The studys authors write that this counterintuitive finding could be a display of post-traumatic growth, leading these men to greater meaning and satisfaction in their later lives.

In WebMDs 2008 survey of centenarians, 84 percent of respondents say that staying in touch with ones spirituality is very important for healthy aging. And follow these 25 Life-Changing Lessons from Super-Successful Men!

A regular short nap dramatically cuts the risk of dying from coronary heart disease, especially for working men. A cohort study of nearly 24,000 people over six years found that occasional nappers had a 12 percent lower coronary mortality, while those who napped at least three times a week for at least 30 minutes had a 37 percent lower mortality.

More than five million Americans are estimated to have Alzheimers diseasea number thats expected to nearly triple by 2050 if there are no significant medical breakthroughs, according to the Alzheimers Association. Theres a genetic basis to Alzheimers, and if the disease runs in your family, its especially important to make changes to your lifestyle to minimize your risk. Just adding more blueberries to your diet can help. Rich in antioxidants that give them their purple or deep red color, the berries protect cells from damage by changing the way neurons in the brain communicate and reducing the accumulation of protein clumps most frequently seen in Alzheimers. In one study, older adults who supplemented with blueberry juice for just 12 weeks scored higher on memory tests than those receiving a placebo. So stock upand fill your kitchen with these 25 Foods to Keep You Young Forever!

According to a study by the French National Institute of Health and Medical Research (INSERM) and University College London, experiencing a traumatic incident as a child could actually make you more likely to die early.

Fill your diet with these 25 Foods Men Over 45 Should Eat!

The link between increased sugar and diabetes risk is right up there with smoking causes lung cancer on the list of immutable medical truthsdespite what soda manufacturers are trying to tell us. But Mayo Clinic researchers have even gone further, saying that added dietary fructoseeither as table sugar or the main component of high-fructose corn syrupmay be the number-one cause of diabetes, and cutting sugar alone could slash deaths from the condition.

A Harvard School of Public Health study showed that older people with the highest levels of omega-3s in their blood lived 2.2 years longer (on average) than those with low omega-3 blood levels. You can find plentiful omega-3 fatty acids in fish, as well as some vegetables and seeds. Salmon is only one of 20 Amazing Healing Foods!

Volunteers may live longer than people who dont give of their time, according to a University of Michigan study. Published in 2013 in the journal Psychology and Aging, it posited that people who give back could be rewarded with lower blood pressure and therefore a longer lifespan.

Several studies have shown that when were reminded of our own mortality, were more likely to make better decisions about our own health, like using sunscreen, smoking less and exercising more. And while youre at it, adopt these 25 Life-Changing Lessons from Super-Successful Men!

Danish researchers discovered that a key predictor of long life in otherwise-healthy middle-aged and elderly men was resting heart rateregardless of fitness level or other health behaviors.

It may be green and leafy, but spinach is no nutritional wallflower. This noted muscle builder is a rich source of plant-based omega-3s and folate, which help reduce the risk of heart disease, stroke, and osteoporosis.

Longevity Welder: Powerful and Lightweight – Pick Welder

Posted: October 13, 2018 at 8:47 am

Established in 2001 in Hayward, California, Longevity Welder has settled on the motto, The Power to Last. This is despite having only existed for what amounts to being a teenager in manufacturing years. The upstart company does not have the age or the prowess of Lincoln or Miller. However, they are turning heads in the welding industry for offering exceptional power in a lightweight form factor.

Through innovation, customer satisfaction, and quality production, Longevity Global, Inc. is determined to gain the trust of its customers. They do it through the quality of their products, their active online presence, including the much heralded Learning Lab YouTube Channel.

And having amassed what amounts to a cult following, Longevity offers a ton of welding info online. This include videos, tips and tricks, a welding forum with lots of photos, stories, and ideas, and DIY templates. Plus, the company is as committed to welder safety as many of its competitor. They offer classes and workshops, instructor training, and more.

But Longevitys real bread and butter comes from aftermarket automotive welders, industrial welders, homeowners, small business owners, and auto shops. Plus, the company and its products was on the Orange County Choppers television show. Indeed they know a thing or two about being thrust into the limelight.

Longevity Welder: Committed to 100 Percent Customer Satisfaction

Longevity Global, Inc. has a diverse product lineup. This includes TIG and MIG welders, welding wire, consumable, safety gear, stick welders and plasma cutters. Their products are suitable for hobbyists, enthusiasts, and professionals alike. Furthermore, their welders and cutters offer powerful performance inside of small, portable form factors.

The company is so confident in the performance of their products. They offer the best warranty – a full 5-year parts and labor money-back guarantee on all welders and cutters. Plus, Longevity encourages all customers to try their products with no commitment for 30 days. At that time, you dont like it, return it with no questions asked.

That is what these new kids on the block consider as representative of 100 percent customer satisfaction. We have to see whether or notLongevity stand the test of time. However, many agree that they are off to a bang-up job already with their price point and their warranty.

Longevity MIG Weld 140 Review

Lets take a closer look at some of their products, starting with the MIG Weld 140. With an MSRP of under $350, this Longevity welder is small and easy to set up. The welder itself weighs a mere 40 pounds and plugs into a standard 110-volt outlet.

If you are not going into the fabrication business and you want a home shop tool, theMIG Weld 140is a great option. This is when you consider that it is $200 less than the Lincoln Power MIG 140. And it is $400 less than the Millermatic 140 Auto-Set.

Of course, we have to bring up the fact that they assemble some of Longevity products in China. On the other hand, they make Lincoln products in Ohio.While Longevity is not beyond reproach for shipping jobs overseas, it is a substantiated business model here in America. In fact, it is the same approach to building equipment that Apple uses.



Our Rating

$ $

While both Apple and Longevity engineer their products in California, they choose to have them assembled in other counties.But regardless where they build the machines, let’s look at how the MIG Weld 140 measures up to some of its competitors.

The Lincoln Power MIG 140, the Millermatic 140 Auto-Set, and the Mig Weld 140 all come with extra tips. This also includes hoses, regulators, electrodes, and adapters. Also, the gear feels solid and made of a good quality material, at least according tothis review. Many of the other specs are also similar when comparing the three welders.

However, the Lincoln is the heaviest of the bunch at 60 pounds, and still cant match the 60 percent duty power cycle at 140 amps. Although both units use 110- or 220-volt power and PFC switch for a generator or secondary power hookup.

Longevity TIGWeld 200Sx Welders

Moving on to TIG welders, these machines are so named for their use of Tungsten Inert Gas. Also known as Gas Tungsten Arc Welding (GTAW) units, TIG welders are reportedly more complicated. It is also time-consuming to set up than MIG (Metal Inert Gas) welding.

This is because the feeder wire and the TIG torch both need to be manipulated manually during the welding process. While the process of TIG welding is more complicated, it also produces the potential for creating finer, more elegant welds with stronger bonds.

Longevity offers both TIG welders and MIG welders, and the Longevity TIGWeld 200Sx is an excellent example of a GTAW welder. Competitors in its class include the Miller Diversion 180 and the Lincoln SquareWave TIG 175 welders.

The consensus is that the Longevity TIGWeld is easier to set up than most. Also, as are most Longevity welders, and it is the least expensive. The Miller Diversion and the Lincoln SquareWave TIG 175 welders are far more expensive at around $1,600 each. Also, the weight differential is huge with the TIGWeld weighing in at around 40 pounds. The Miller taking welterweight at 50 pounds, and the Lincoln coming in with the heavyweight title at 185 pounds.

Other notable disparities include differences in duty cycles, which, as mentioned, was 200 amps at 60 percent for the TIGWeld. It is 150 amps at 20 percent for the Miller, and 150 amps at 25 percent for the Lincoln. The Lincoln Squarewave TIG 175 also only runs on single phase 220 power. On the other hand, the two welders can run on either 220 or 110 phase power.

In addition to powerful duty cycle, TIGWeld Longevity welders come with TIG torches made by Weldcraft. It isa standard name in the welding community known for high-quality and durable products. Also, all Longevity TIG welding machines feature stick welding capabilities at the flip of a switch.

Longevity Stick Welders, Lightweight Powerhouses

Stick welding, or Shielded Metal Arc Welding (SMAW), is one of the oldest types of welding known to man. The processis simpleand produces strong welds that can be used to fasten together thick chunks of metal.

Also, stick welding uses a single electrode and consumable rods to produce molten metal that acts as an adhesive as it cools. It is common to go through many rods in a single welding session. The weld produced are rarely ever attractive like TIG welds, but they are extremely strong.

These are the types of welds you would see on a construction project, used in bridge work, or for support girders in building structures. Think about heavy machinery and industrial metals when you think of stick welding.

A much cheaper form of welding than the other applications, stick welding can also be applied outside during inclement weather and to pipes and plumbing. However, SMAW is also messy and leaves debris and slags all over the project. The heat and power created during the process are great for joining chunks of iron. They are going to burn up thin materials like aluminum or stainless steel.

It can be extremely useful, though, to have a stick welder in the garage, andLongevitys StickWeld 140 is an excellent choice. With an MSRP of $279.99, the entire unit weighs only 13-15 pounds, and it runs off from the two most common power phases: 220 and 110 volts. With the same duty cycle as the TIGWeld, some reports say that if you run rod after rod for 10 minutes straight, the machine will overheat. But, by and far, most other accounts say this featherweight is a champ.

Plasma Cutting with Longevity Welder

So far, we have covered how to bind metal together. Now we are going to dive into tools that will cut it apart. There are many reasons for using a plasma cutter for slicing through metal. Two of those reasons are speed and efficiency. Compared to an oxy-acetylene gas cutting torch, plasma cutters are cleaner and faster. Plus, an operation is far less costly.

Longevity has offered professional plasma cutting equipment for almost 20 years. Their proprietary Blow Back Pilot Arc technology makes cutting expanded metals easier as well as enables easy arc strikes. Plus, the Longevity ForceCut promises to produce less slag and a stronger arc than its competitors. What is more, it even operates from any air compressor with a minimum of 70 PSI and 3.0 CFM.

Moreover, the entire unit weighs about 25 pounds, and it works off from 110v or 200v power at about 40 amps. Also, the Blow Back Pilot Arc allows you to safely fire the plasma gun in tight spots. Similarly, around sensitive equipment like computers, CNC tables in classrooms. In addition, to communications devices without worrying about causing damage to any of the equipment.

Longevity Welder: Wrapping Up

Sure, Longevity does not have the heritage that Lincoln does, but now that you have seen some of their products and how they stack up to the competitors, you can make an informed decision about buying your next welder or cutter.

Longevity keeps their welders and cutters lightweight and powerful, thanks to their new inverter technology and IGBT chipsets. The IGBT module stands for insulated-gate bipolar transistor, and it is a high-performance 7th generation chipset that is designed to be small and compact and provide for greater power output than in previous generations. The product is manufactured by Fuji Electric, and it is reported to be environmentally friendly and RoHS-compliant.

In addition to offering new technologies, like improved power through new inverters, Longevity offers the best warranty in the business – a 5-year parts and labor warranty on all of their products. Plus, you can try any of their welders or cutters for free for 30 days.

They might be fledglings in the esteemed blue-collar business of welding, but they are turning some head and impressing customers with their lightweight and powerful products. The fact that Longevity has created welding products that can keep up with (and sometimes surpass) the power produced by similar units made by manufacturer royalty is impressive enough.

Sure, Longevity Global Inc. assembles their products overseas, which is a business choice that is going to offend some buyers, but hopefully, as this blog suggests, that does not diminish the quality of their products. And in an era of iPhones and mobile devices and portable everything, these lightweight, mobile welders might just earn Longevity the staying power it so desperately craves.

What does longevity mean? –

Posted: October 13, 2018 at 8:47 am


The word “longevity” is sometimes used as a synonym for “life expectancy” in demography – however, the term “longevity” is sometimes meant to refer only to especially long lived members of a population, whereas “life expectancy” is always defined statistically as the average number of years remaining at a given age. For example, a population’s life expectancy at birth is the same as the average age at death for all people born in the same year. Longevity is best thought of as a term for general audiences meaning ‘typical length of life’ and specific statistical definitions should be clarified when necessary.Reflections on longevity have usually gone beyond acknowledging the brevity of human life and have included thinking about methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopian novels.There are many difficulties in authenticating the longest human life span ever by modern verification standards, owing to inaccurate or incomplete birth statistics. Fiction, legend, and folklore have proposed or claimed life spans in the past or future vastly longer than those verified by modern standards, and longevity narratives and unverified longevity claims frequently speak of their existence in the present.

Regenerative Medicine New York | Stem Cell Therapy

Posted: October 11, 2018 at 7:46 pm

Stem cell therapy is a form of regenerative medicine that utilizes the bodys natural healing mechanism to treat various conditions.

Stem cells are being used in regenerative medicine to renew and repair diseased or damaged tissues, and have shown promising results in treatments of various orthopedic, cardiovascular, neuromuscular and autoimmune conditions.

Stem cells are present in all of us acting like a repair system for the body. However, with increased age sometimes the optimum amounts of stem cells are not delivered to the injured area. The goal of stem cell therapy is to amplify the natural repair system of the patients body.

There are two major types of stem cells embryonic stem cells and adult stem cells. Embryonic stem cells (ESCs) are stem cells derived from human embryos. They are pluripotent, which means they have the ability to develop into almost any of the various cell types of the body.

As the embryo develops and forms a baby, stem cells are distributed throughout the body where they reside in specific pockets of each tissue, such as the bone marrow and blood. As we age, these cells function to renew old and worn out tissue cells. These are called adult stem cells or somatic stem cells. Like embryonic stem cells, adult stem cells can also replicate into more than one cell type, but their replication is restricted to a limited number of cell types.

The unique self-regeneration and differentiating ability of embryonic stem cells can be used in regenerative medicine. These stem cells can be derived from eggs collected during IVF procedures with informed consent from the patient. However, many questions have been raised on the ethics of destroying a potential human life for the treatment of another.

Adult stem cells are most commonly obtained from the bone marrow, specifically the mesenchymal stem cells, which have the ability to replicate into cells that form the musculoskeletal system such as tendons, ligaments, and articular cartilage. They can be obtained from the iliac crest of the pelvic bone by inserting a needle and extracting the stem cells from the bone marrow.

Currently, stem cell therapy is used to treat various degenerative conditions of the shoulder, knees, hips, and spine. They are also being used in the treatment of various soft tissue (muscle, ligaments and tendons) as well as bone-related injuries.

You may be a good candidate for stem cell therapy if you have been suffering from joint pain and want to improve your quality of life while avoiding complications related to invasive surgical procedures.

The procedure begins with your doctor extracting stem cells from your own bone marrow. Bone marrow is usually aspirated from your hip region. Your doctor will first clean and numb your hip area. A needle is then introduced into an area of your pelvic bone known as the iliac crest. Bone marrow is then aspirated using a special syringe and the sample obtained is sent to the laboratory. In the laboratory, the aspirate is spun in a machine for 10 to 15 minutes and a concentrated stem cell sample is separated.

Your doctor then cleans and numbs your affected area to be treated and then, under the guidance of special x-rays, injects the stem cells into the diseased region. The whole procedure usually takes less than one hour and you may return home on the same day of the procedure.

The disadvantage of adult stem cell therapy is lack of data about its long-term effects as it is a newer evolving therapy.

Stem cell therapy is generally considered a safe procedure with minimal complications, however, as with any medical procedure, complications can occur.

Some risks factors related to stem cell therapy include infection as the stem cells may become contaminated with bacteria, viruses or other pathogens that may cause disease during the preparation process.

The procedure to either remove or inject the cells also has the risk of introducing an infection to the damaged tissue into which they are injected. Rarely, an immune reaction may occur from injected stem cells.
