Why do some people float on water easily when others a similar size can’t?
We're mostly water, so it doesn't take much either way to make us dense enough to sink, or a little more buoyant to float. I found out when I was little that I was almost neutral, and could float if I filled up my lungs, but would sink if I emptied them, scaring the lifeguards at the pool, so it'…
The Short Answer
We're mostly water, so it doesn't take much either way to make us dense enough to sink, or a little more buoyant to float. I found out when I was little that I was almost neutral, and could float if I filled up my lungs, but would sink if I emptied them, scaring the lifeguards at the pool, so it's a pretty close balance. Women tend to be more buoyant than men because they have a bit more body fat, percentage-wise, than men, and fat is less dense than water. Fat is likely most of the difference generally because other tissues don't vary in amount and density all that much, unless you're looking at bodybuilders, who probably don't float very well.
