Submarine-- life and death

I had an interesting chat today with a submarine medical officer.  He told me that 4 out of every 1,000 seamen die right after they serve on a submarine.  Two reasons: 1) They get really drunk after months on a dry ship.  2) They get in car crashes.  Submariners are not allowed to drive for a week after their service because for months, their eyes had not focused on anything that's more than 100 feet away.

Here's a quick peek at life on a submarine.  I wish I had written down everything he told me about the superiority of diesel versus nuclear subs.
