Of course long life is all those things that you don't care to raise, like IQ, etc. As a for instance, several researchers believe that IQ simply reflects brain "health" - that IQ 140 means nothing wrong, and less than that is the sum of all things that have not gone wrong.

So, longevity (survival) is a function of the organism in its environment - you can't raise it in the abstract.

More narrowly, longevity as the all-things-being-equal ability of system to repair themselves is at this time an almost completely open question. No one knows the answer. Hope for master clocks at both chromosomal and organismic levels (with melatonin as a regulator for instance) and such-like remains strong but largely unfulfilled.

so .. go and donate lots of money to a research institute that you like ;-)


"Apple's bundling of Apache is terrific to see," said Brian Behlendorf, co-founder of the Apache Group, the development team behind the Apache web server, as well as CTO of New Ventures at O'Reilly and Associates. "But this is more than just about bundling. Engineers from Apple have been working with other Apache developers on Mac OS X support, as well as adding functionality that has helped all Apache users. This is precisely how the 'Open Source' model works, and it's wonderful to see Apple fully embracing this. They have been an exemplary participant in the process."
