Olympiclifter1992 saidI probably would, however it's an interesting thing to consider. The majority of negative side effects associated with aging are lifestyle issues. Therefore it's deconditioning, not actually getting older, that causes the so called "aging" process. Genetics do play a role for sure. But gaining weight as you get older is generally due to less physical activity and an increase in caloric intake. Poor skin is usually the result of not taking care of your skin by moisturizing, and overexposure to UV radiation (not judging cause I like everyone else have used a tanning bed). Not to mention the effect that smoking, drugs, and alcohol have on our internal organs and on our physical appearance. So really it seems that we already have the necessary tools to prevent or halt the aging process. The problem is that we don't want to put in the hard work.
Longevity is almost entirely genetics. Dogs have their short lives because of their genes and ours are longer because of ours. If someone were to live the perfect life as per your description they might look
better when they reach 80, for example, but in the end it'll be their genes that cause the eventual failure of their body. Eating poorly, being sedentary, and such may shorten your life but no amount of perfect living, vitamin supplements, healthy eating, exercise, etc. will let you live longer than what's programmed into your genes.
