If you Google “Who is the toughest Navy Seal ever?”, David Goggins name comes up. His nickname is “The Toughest Man Alive” and if he’s not the very toughest he’s definitely up there. This is his follow up book to his bestselling “Can’t Hurt Me” and follows a lot more of his ultra racing. His story is pretty well known to a lot of people by now, but worth reading if you’re at all interested in what the human body and mind are capable of.
