This was worth all 18 minutes of it! I thought it was going to be another one of those telomere talks which I think "popsci" puts too much emphasis on. I would be interested in a post on aging. I think two things that would be interesting to study in regards to aging are hormone changes and gut bacteria. I am not saying there is a difference in gut bacteria or even that it has any implications on the aging process but it would be interesting to study.
