We've all heard of Methuselah, the wandering Jew who lived for centuries. Then of course there is the fountain of eternal youth and hundreds of other longevity myths for every culture on the planet. Humans are enamored by the idea of living forever. Hasn't it crossed all of our minds at least once how we wish we could turn off our natural clocks and stop the aging process for a year or a decade or even a century? How cool would it be to live a couple centuries and chronicle actual change? Or abstract even further and live long enough to see species evolve? That would be awesome. "Hey Tommy, you remember way back when, before Bears had wings?"
But these are just dreams, living forever is impossible. Or is it? Dun dun dun... About a year or so ago was when I first started hearing scientists assert that a calorie-restricted diet could increase one's lifespan. The statistic I remember reading was that if a person eats 30% fewer calories than he might end up living 30% longer. So, by saying no to one meal a day you can stay on this planet for 20-25 more years. Sounds good to me. Today I read a follow up article about a drug that has been tested on mice and worms which simulates the calorie restricted diet without the actual requirement of the calorie restriction. Imagine that, a once-a-day pill to live 30% longer.
Obviously we are years away from actually seeing something like this if at all, but I find the question on whether or not I would take it fascinating. So would I, would you? Is it even an ethical question at all? I think it is just a smaller question inside a larger debate about the proper border between science and nature. If we can do this one small thing which doesn't seem so bad or dangerous, then where should we draw the line? If we can choose to cheat death a bit longer why can't we as parents chose which genes our children get? In my opinion the moment we allow one departure from our natural condition than we are opening a floodgate for the tinkering of our definition of the word human.
But if the option were offered to me today, to live 30% longer, I don't see any reason that would prevent me from accepting. Every living thing in the world cycles cells continuously throughout their entire life. The cells and atoms that comprise your unit today will not be the ones there 10 years from now. So why do we die? We're like an apple product, built in with an automated death process. If the human genius can successfully turn that process off, why shouldn't we?
