How long can you hold your breath?

[IronFist]

Not that it will necessarily help you servive a choke, I'm just wondering what average is.

I'm talking your absolute max, so if you've been sparring for 5 minutes first it probably won't be as long. Say you have time to prepare, so can hyperventilate first or whatever to help. Careful, don't pass out.

I saw this show on tv about these women in Japan who are coral divers or something and can hold their breath for like 2 or 3 or maybe it was 5 minutes. I don't remember, but it was a really long time. They learn some technique to slow down their metabolism and therefore don't require as much oxygen. They go down really deep (ow my ears!) and get pearls or something. Sorry I don't remember it too well
