Sure, right after you sterilize stupid people so they can't have children.... Denying the over 40 crowd from doing anything because of their age is simply discrimination!
I'm 56 and this year like every other I passed a saturation diving medical. There are 25 year old divers on this discussion board who couldn't do that. So your suggesting that because I happen to be over 40, you think it's wise to deny me the chance to dive (and to make a living)??? I obviously don't agree!
I think it would be better to deny those who don't want to spend the time to learn how to do an activity properly.
As a side note I can't believe that you still sat dive and you are 56! Keep kicking ass man!
