diving air to 210 feet??

[Tomeck]

Talking about Cousteau.... True, but Cousteau was the anomaly. Do you know how many of his dive buddies died of dcs with him? Of the top of my head, it was over 30. He had an amazing physiology.

Yes, his friend died at 130 meters (428 feet).

"100% not toxic @ 20' "?
"O2 is toxic for all living things," at all depths regardless of pressure....
"for if they breath it they will one day die"!

That' it. I quit...going cold turkey no more O2 for me.
