My husband "gave" me scuba lessons as a birthday gift a few years ago. It had been a rough year -- my father died suddenly, I was in a fog, work was depressing, life was sort of ugly.
So, we took lessons and even though I have claustrophobia (yes, every time I descend, I have a little anxiety), I stuck with it. I didn't pass my written test the first time, so I could only do the first day's worth of diving in Monterey, CA (water close to 60 and air around 75). So, I passed the test the next week and then had to finish my last dives at Lake Tahoe -- which combined altitude into the mix, not to mention the fact that it was snowing and the water was a brisk 53 degrees.
We left two weeks later for the "real" surprise -- he took me to St. Lucia and we hit the 80-degree water with rapture. Been diving ever since and loved it. It restores my sanity (although some would argue that point).
I even "challenged" my UW claustrophibia and did the Cathedral I dive @ Lanai ... I did a few swim throughs and survived -- okay, so I sucked a little air a little quicker, but I still managed it and came back with close to 1500 PSI (you know how those guided tour dives are).
I'm now doing underwater photography and just got an UW video to start learning something new.
And, as an aside, my dad was an old Navy man and his ashes were scattered at sea. So every time I dive, I say hi to him as well
