There are some good bits, but the author seems to have a habit of a few ego-fuelled rants here and there. In addition, the conclusion on what to do from now on is a bit anti-climatic: "eat, exercise, and fund the ageing research". There's not a whole lot of action-steps to be taken there.

If you're interested in ageing, this could have some potentially interesting information on the mechanics if you are willing to look past the overly hopeful writing tone and egocentric rants.
