A lot of the breakthroughs in this book seem too good to be true, and I've read elsewhere that the results discussed are controversial and no one else seems to have reproduced them, which tracks even if it's disappointing.

This book came out in 2019 and makes a few references to a "future pandemic" that raise eyebrows in 2024.

Overall I'm glad I read it, and I hope the author is right about our imminent ability to slow/reverse aging and keep folks healthy and hale into their 100s but I'm not exactly holding my breath.
