Hey Pete, that's your standard game so don't complain when it is reasonably used right back.
We were talking about team behavior and drinking and diving. Both are constrained with a scientific diving program.
Bob suggested that, "I think trying to impose the constraints of a scientific diving program on a recreational activity is an exercise in futility."
You added, "Not to mention how it would destroy the dive industry."
Now, we were talking about team behavior and drinking and diving, not something controversial like actually having divers who know how to dive and who are really prepared for the environment(s) that they will dive in or actually know enough about the actual risks to to reasonably provide informed consent, we were talking about drinking ... plain and simple.
Thus, reasonably and logically, I suggested that, "Oh, so not drinking before diving and being responsible for your team mate are exercises in futility that will destroy the dive industry?
I submit that quite the reverse is the case, the danger comes from those who thinking drinking has no effect on your hydration and that you have no more obligation to your teammate than possibly, if convenient and fun, providing yet another redundant air source."
Clear?
