The fat in your body does tho, regardless of how skinny you are. Think about how people try to "bury" dead bodies in water and how they seem to float up at the worst times lol
Right but you still have fat in you and water, and bone, and muscle, all of which combine to inform my assertion that you cannot sink if you simply lay back and allow yourself to float. You also have 2 natural floatation devices which as a male I am not blessed with ;)
Presumably even taking your underweightedness into account
Oh yeah, those two little buddies hanging out down below my shoulders. Well I guess, supposing I do find myself in a situation involving it, I'll naturally keep people here up to date on if water wins out.
I was gonna do one on if tits help women float better in water but got around to this one first cuz i have a busy day and the other ones gonna be more relateable and densely answered methink
