Snorkeling in a Cenote in the Yucatan: They told us to follow one another in a line. Of course I decided it would be a better view if I went over to the left side.

My snorkel hit the roof of the cave, which caused me to reflexively move my head and fill the snorkel with water. At which point my head and body pinned against the roof the cave and I could not rotate my head back to put the snorkel in air, or move.

I thrashed about for what seemed like minutes but was probably about 10 seconds. Then suddenly I had a sense of total calm, "Okay, let's figure this out or we are doing to die." I stopped thrashing, and started to push myself back towards the center of the cave where I could surface. Just as I hit clear air, fortunately, the guide in the back of the group reached me at the same time and helped make sure I was going to stay in the line.

My kids were there and just shook their heads - their dad is an idiot.
