Another number related aside. I have this dive computer. Got it when I started working in the dive industry in, what, 2002? Began using it when I was working in Hawaii in 2003 or 4. It goes with me on just about every dive I make, and continues to be a faithful companion, easing me back to the surface without allowing me to froth my blood with nitrogen. It has a history function that keeps track of the number of dives it has made and the amount of time it has spent underwater. Every once in a while I access it for a chuckle; when it got close to 1000 dives, I started paying close attention to it to see what it would do. After 999 it goes back to...1. That was 999 dives ago. It rolled over to one for the second time, and has now attended 2000 dives and spent 1715 hours underwater. That, my friends, is a lot of nitrogen. No wonder my brain is turning into Swiss cheese.
