Lifespan by David Sinclair is an awesome book about how we can extend lifespan and the implication. Optimism abounds with Sinclair, but his research does keep him somewhat to the ground.
For many later parts in the book (the speculative/extrapolations) it’s difficult for me to judge where we’re going. But I dearly hope that he is right and that we will be living much longer than our parents.
And yes, that is healthspan, not only lifespan. Or in other words, I want to live in a healthy body, not extend the last phase forever.
At a later date, I will write down more extensive notes (when the longevity theme – 2020 goals – comes around).
Here is another good summary.
