And what about people like David Blaine or Tom Sietas? Sietas held his breath underwater for over 22 minutes (world record). I know they train for it like months and even years, but doesn’t holding your breath = no oxygen to brain?
Permanent brain damage apparently occurs just after 4 minutes of lack of oxygen to the brain, so why are freedivers left generally unscathed after 8 or 10 minutes without air?

My dad smoked almost his whole life, starting from a very young age. In his 40s he could hold his breath under water for about 4 or 5 minutes. I’ll be 40 this year, never smoked a single cigarette and can only hold my breath under water for about a minute tops.
