Funny one!
Herbert, you were quite mercyless with the showman. He almost fainted with that kind of hyperventillating.
This is the type when you take only little air with a big effort. This could eventually reduce the oxygen level, as I know.
So the poor showman almost fainted, at least as I saw.
Kars, Herbert also mentioned the freediving just for fun. May be he could have talked about the fishes, corals, shipwrecks, the Arch. But being on a show it is not so easy to talk about what you want (in that depth, what you want especially), I can tell you..
