From the Ted Talk by Cynthia Kenyon: Experiments that hint of longer lives

Unscramble the Blue Letters

So maybe it's working in people the same way. And there are hints of this. So for example, there was one study that was done in a population of Ashkenazi Jews in New York City. And just like any population, most of the people live to be about 70 or 80, but some live to be 90 or 100. And what they found was that people who lived to 90 or 100 were more likely to have daf-2 mutations — that is, changes in the gene that ecodens the receptor for IGF-1. And these changes made the gene not act as well as the normal gene would have acted. It daaegmd the gene. So those are hnits suggesting that humans are susceptible to the effects of the hnrmooes for angig.

And what they found was that people who lived to 90 or 100 were more likely to have daf-2 mutations — that is, changes in the gene that _______ the receptor for IGF-1. And these changes made the gene not act as well as the normal gene would have acted. It _______ the gene. So those are _____ suggesting that humans are susceptible to the effects of the ________ for _____.

And what they found was that people who lived to 90 or 100 were more likely to have daf-2 mutations — that is, changes in the gene that encodes the receptor for IGF-1. And these changes made the gene not act as well as the normal gene would have acted. It damaged the gene. So those are hints suggesting that humans are susceptible to the effects of the hormones for aging.
