It's depressing, that those junk food eating fat people live to be so old. You do not gain so much by living healthy your whole life. In their youth the junk eating people have as good life as you, because when you are young the healthy habits do not matter so much. When you start having noticable advantages over those people, you are old anyway, and junk food eating young people have a much better life than you. :D
Actually the benefits are not as small as most make them out to be, and if you've not gotten lucky in the genetic lottery, the benefits are even bigger.
When people push into their 100s, in general it is because they've not been dying in some bed in their 70s. Many of them you hear living independent, riding bicycles, running, etc.
Obesity carries with it likelyhood of metabolic syndrome with all the health complications that entails, and those can start even in your 30s.
Lifestyle factors appear to be the main cause of men gaining similar likelyhood as women of becoming a centenarian.
In this promising time anyone below 30 that reaches centenarian will experience the benefits of 70 years of technological progress.(2080)
Overall, the men[centenarian] were functioning better than the women. Nearly three-fourths of the male survivors could bathe and dress themselves, while only about one-third of the women could.
The researchers think that may be because the men had to be in exceptional condition to reach 100.
A second, larger study of men in their 70s found that those who avoided smoking, obesity, inactivity, diabetes and high blood pressure greatly improved their chances of living into their 90s. In fact, they had a 54 percent chance of living that long
Their survival decreased with each risk factor, and those with all five had only a 4 percent chance of living into their 90s, according to Harvard University researchers.
Those who managed to avoid lifestyle-related ailments also increased their chances of functioning well physically and mentally two decades later.
In fact, researchers have detailed an astonishing longevity hot spot in which they have documented 90 centenarians among a population of 18,000. That means that one out of every 200 people in Ogliastra has lived to celebrate a 100th birthday. It’s an extraordinary figure, about 50 times the rate of the United States, where only one person out of every 10,000 people lives to see 100.
“These are people who not only have a very long life, but they are healthy up to a very old age,”
says Luigi Ferrucci, chief researcher of longitudinal studies at the U.S. National Institute on Aging (NIA) and a co-author of the Ogliastra study. “These are not people who’ve gotten diseased or dementia at 70 years old and somehow lived another 30 years.
Ninety percent of the centenarians studied in the New England Centenarian Study were functionally independent the vast majority of their lives up until the average age of 92 years and seventy-five percent were the same at an average age of 95 years. Similarly, a study of US super-centenarians (age 110 to 119 years) showed that, even at these advanced ages, 40% needed little assistance or were independent.-wiki
Strikingly the F/M ratio among centenarians in this population is close to one, as 47 male centenarians were found and only 44 female centenarians. Thus the LGG usually observed among the oldest olds in other populations is virtually nonexistent in the longevity Blue Zone.-http://www.hindawi.c...ar/2011/153756/
There is no real science behind this longevity-religion. Present day science can really do nothing about aging.
You talk as if there were fundamental barriers, as if the foundation of the science that will halt aging did not exist, when all points otherwise. What tell, will stop the science of tissue engineering? Of cell therapies? Of genetic engineering? I can tell you this unless fundamental barriers appear, these 3 can yield biological immortality, aka, negligible senescence.
Already science has intervened in the aging process of other creatures from single cells, to worms, to flies, and even to mammals. And the deeper understanding of biology will allow real interventions to be developed.
Present day science can replace sphincters, heart valves, can deal with organ failures, replace hips and joints, many aspects of decay can be dealt with to varying degrees. Even bladders have been replaced.
Other organisms are providing hints as to some of the keys evolution uses to go from aging to nonaging negligible senescence
