It would be great to stay young. I'm happy to report that scientists have been seriously testing if stuff actually works for over a century (Slonaker, 1912).

It would be great to stay young. I'm happy to report that scientists have been seriously testing if stuff actually works for over a century (Slonaker, 1912). They typically try an intervention, like diet or exercise, on lab animals, and then see how long they live. For what it's worth, I maintain the world's biggest spread sheet of these life span experiments. It summarizes over 14,000. One column is the intervention (diet, exercise, etc..) another is the change in lifespan (+10%, -2%, etc...) another is the species (human, mice, etc...) and so on. It's interesting to see what works. More info is at http://morse.kiwi.nz/kingsley/doku.php?id=science:start http://morse.kiwi.nz/kingsley/doku.php?id=science:start
