Before I can tell you what happened to me, I first must bore you with a few technicalities of my job. As you know, my office lies at the bottom of the sea. I wear a suit to the office. It's a wet suit. This time of year the water is quite cool.
So what we do to keep warm is this:
We have a diesel powered industrial water heater. This $20,000 piece of equipment sucks the water out of the sea. It heats it to a delightful temperature. It then pumps it down to the diver through a garden hose, which is taped to the air hose. Now this sounds like a darn good plan, and I've used it several times with no complaints.
What I do, when I get to the bottom and start working, is take the hose and stuff it down the back of my wet suit. This floods my whole suit with warm water. It's like working in a Jacuzzi.
