Hey, I have a few questions about freediving. They might seem a little stupid, but I am curious. First, is it true that unlike scuba diving you aren't supposed to exhale a lot as you surface? Second, Are there any good methods to learning how to hold your breath long? On average I can only hold mine for about 1:15. And third, are there any risks to freediving like the bends or something, like here is in scuba diving? Thanks!
