Genesis once bubbled...
IF this was not a medically-induced problem (that is, it was not a matter of "fitness to dive" from a medical perspective) then I think you're WAY off base WW.
That Snuggles admitted to screwing the pooch (and nearly having it cap him or her) doesn't mean that he or she is the only one who has done it. Quite the contrary. Many divers have at one time or another done something boneheaded and had something bad happen as a consequence.
We all calibrate our personal risk tolerance in partaking in this activity. Then again we do it crossing the street too, and yet nobody gives you a hard time when someone runs you over and breaks both of your legs while you're walking to the store.
Something has happened here in the last few weeks, and I'm not sure I like it. I have read the SeaJay/Mike war, along with a few others. There's a definite "sea change" afoot here that is, IMHO, negative in its impact in that there is developing a STRONG discouragement towards people reporting not only the good, but also the bad and the ugly.
Yet how do we all learn except to see the bad and ugly, along with the good? We don't, and that is a major problem!
Bill, you may well have someone have a seizure on you underwater due to O2 tox or due to an UNKNOWN medical issue. If you are unwilling to dive with someone, then dive solo. Part of being a buddy is that you may get saddled with an unexpected emergency situation - that is part of the reality of BEING a buddy!
If you want to quiz your potential buddies on their "fitness to dive", go right ahead. But what if someone who you just met on the boat decides they'd rather not deal with that kind of inquiry, as they deem it overly intrusive, and that leaves you diving solo?
