The frustrating thing about wellness is that wellness influencers are subject to a similar level of bad incentives as everyone else. Maybe it's because wellness is not sexy. Sit less, exercise more, eat more vegetables, but then the people who get attention are the "one neat trick folks who want to tell you about something you _don't_ know." And I'm sure Bryan Johnson knows some things your average person doesn't. but is 2% good, 98% crap and he doesn't know which 2% is good?
Point being that maybe the surgeon general should be a wellness expert, but there's as much if not more corruption and snake oil in wellness as their is in big pharma.
