Radiolab

Are there any references for the tradition of 'Obaa-siteh' that was introduced in this segment? I can't find it anywhere.

I'm writing a paper on the -alteration of genes for less aging and longer life- for a class. Any additional information or sites where I can find additional information?

Thanks-

I was intrigued by the Mortality podcast, but I was also disappointed that you did not take it as far as you could have. Unlike other RadioLab broadcasts, I was left with many unasked (and unanswered) questions.

For example, if the worms can have their life extended and be youthful and energetic, then things become an issue of morbidity not mortality? Part of the problem of old age as clearly demonstrate in the broadcast is inability to care for oneself, but the worm experiment seems to suggest that one can remain vigorous till the end. What would it mean to have an aged, yet functional society? Why would you need to get rid of the aged if they can still care for themselves?

Also, what evolutionary benefit is there to aging? Why would there be that gene that suppresses the youthful genes? Also, what is the relationship with reproduction and youth? Do people who don't reproduce stay more youthful? How about pets who are spayed before sexual maturity? What is the relationship between reproduction and aging? (The worm segment talked about greater youthfulness related to inability to reproduce?)
