We don't drink the air, so always make popular buddies
It's a great talking point and ice breaker, as you said smrtblndiver, people do look at you differently once you let them know your hobby, especially in my profession.

We are also more aware of our limits so are less inclined to get ourselves into hot water, or more likely to get out if things aren't looking right.
