I'd recomment "The First Immortals" by Halperin as a good read for anyone interested in the idea of science providing answers to physical death in the near term future. It is a novel, but well researched.
I'd also recommend "The Truth Machine" by the same author as a future history where we have been able to 100% detect when someone is lying, and what that would mean to society.
Thanks for the suggestions!
"The First Immortals" by Halperin is already on my to-read list.
I will include "The Truth Machine" on the list as well.
