That is the guy who wrote the extremely popular book Body for Life. Former competitive bodybuilder, supplements peddler, etc, etc. Ok, he was in his 50's, not 20's, but a super-fit health nut - which is probably the only reason he survived.
My wife is friends with his brother's ex, and received a more detailed, grueling account, which sounded hideous (and extremely touch-and-go), and included yet another "I regret not getting the vaccine," statement, from the hospital bed. Ironically, dude had been training hard for some peak or other at the time he got infected, saying, "I hope to be at my peak of fitness by the end of July...god willing."
