I have mentally touched on this field many times in the past but never taken the time to look into it. Conceptually the fact that some animals live for days, while others live for decades has made me certain that longevity could be "easily" influenced through biological manipulations. The fact that a Mouse is 'closely' related to humans, yet lives for 3 years, and humans live for 80 implies to me that mice should be able to easily be extended out to 80 or so years if we only knew the secret to human longevity.
And so similarly, of course, when I look at other species which are supposed to live for several hundred years (like some turtles and some fish) I think that ideally we would be able to study them and find their secret, and apply it to ourselves somehow.
Anyway, thanks to olarsson making a request for a paper on this topic in the full member section, I managed to find this site:
http://www.agelessan...s.org/index.htm which seems to have some interesting information on it.
I have only just started looking through it, but thought someone else might be interested in it too, and maybe something worth discussing will come up.
