Most people are slightly positively buoyant with their lungs full. you can test this in deepish water by standing straight up in the water like a hydrometer and see where you settle down its usually somewhere between your eyes and your chin if you are higher this means you probably have an excess of fat if you sink you have very little fat. swimming or treading water gently will easily keep you afloat to breathe.If you fully deflate your lungs you should sink. If you don't again you probably have a excess of fat.
