A dose of common sense from calorie restriction (CR) practioner April Smith: "First, no one I know thinks that true immortality is a possibility. There will always be accidents ... However, there are some very reasonable people who believe that it is possible that technology will advance enough to defeat many of the mechanisms that cause aging. If we could repair the damage of aging, then we could dramatically extend life and health. I believe that would be a very good thing. ... Before I got involved in the CR Society, I wasn't aware that these perspectives existed. I was hopeful that CR could help me look forty at fifty-five, or at least help me not feel like total crap at 29, but I didn't even think about radical life-extending biomedicine. ... but there are quite a few who hope that by pursuing vigorous CR, we might live and be in good health at a time when more advanced medical technologies are available to extend healthy life further. For those who dismiss this as childish fantasy, I ask on what basis they make that determination. ... I can attest that I was quite unaware of the real progress that has been made in recent years, and when I found out more, my perspective changed."
