mweitz:My question is, what does she do at 160' when her "trust me" guide has a heart attack?
I think that you should never dive in a situation where you can't take care of yourself by yourself. Even though the guide may be a "pro" the unexpected can happen to all of us.
Thinking that you are immune from the unexpected due to your experience and education level is when you become truly dangerous IMNSHO.

So I guess I should not fly in a plane untill I learn to land it by myself in case the pilot should have a heart attack?
