And that's a limited thing as well...
I guess we should take this as a suggestion to fund SENS with all the money we spend on things like Gym Memberships, supplements and so on.

Contrary to what is often said in popular books and promoted on TV and the internet, neither antioxidants, nor resveratrol, nor human growth hormone, nor any exercise or conventional dietary regimen even “slow down” the aging process, let alone reverse it; and, actually, I’m afraid your options are limited even in terms of slowing it down.It’s important to understand that no conventional diet, no fitness regimen, no supplement affects the aging process “itself,” or will have more than a marginal impact on life expectancy or years of end-stage frailty and decay.
The only possible exception to this is calorie restriction (CR) — i.e., eating a diet that is unnaturally low in calories, but carefully engineered to have 100% of the organism’s requirements for vitamins, minerals, protein, and essential fatty acids — which as you may know is the most robust of the very small number of interventions available now that is known to slow down biological aging in mammals. Aside from that uncertain gamble, and to have a really substantial effect in people who are already of middle age and above, we need radical anti-aging biomedicine.
Aging is, by its nature, a product of basic metabolic processes which aren’t appreciably altered by environmental influences, and it’s for this reason that, whereas genes only account for about 25% of your chances of reaching an age of about 75, they are a HUGE factor in your odds of becoming a centenarian once you have already lived that long, rather than dying shortly thereafter: at that point, it’s all about basic aging, with little influence of environmental factors.
That doesn’t mean that taking care of yourself is worthless. Eating well and exercising will greatly reduce your odds of suffering “prematurely” with many “age-associated” disabilities and diseases (such as heart disease, diabetes, and some cancers), and because of that, lifestyle factors are major predictors of your odds of reaching what was once ‘old age’ — 75 years or so, which is now actually below average. However, this has relatively little to do with aging, and a lot to do with killing yourself early with self-abuse.
As to what to do to avoid hastening age-related disease: boring as it sounds, the best advice is the stuff on which the public health people and all the diet gurus from Atkins to Ornish all basically converge: not smoking, lots of fruits and vegetables, lean protein, keeping yourself slim, olive oil as your main fat source along with fatty fish or a little flax oil, a glass or 2 of wine with dinner, avoidance of trans- and (over Atkins’ equivocations) saturated fat, “moderate” cardio and resistance training, a positive outlook, and so on.
