“Don’t Die”

"Don't die" sounds quasi-religious. But "Stop killing yourself" might be a better slogan, to frame it as: stop smoking, stop drinking, stop overeating, get moving, go to bed, etc. Or framed another way: is it weird that Bryan Johnson is so healthy? Is it reasonable to assume that the average 50 year-old American cannot run a 10-minute mile? 8-minute mile?
