I was eeling my way through the lobster-caves, with a borrowed bottle and mask. I'd also borrowed a wetsuit, but I wasn't wearing it -- the blood-temp salt water was balm, and I hated erecting barriers between it and my skin. The caves were made of coral and rocks, and they coiled and twisted like intestines. Through each hole and around each corner, there was a hollow, rough sphere of surpassing, alien beauty. Giant lobsters skittered over the walls and through the holes. Schools of fish as bright as jewels darted and executed breath-taking precision maneuvers as I disturbed their busy days. I do some of my best thinking under water, and I'm often slipping off into dangerous reverie at depth. Normally, my diving buddies ensure that I don't hurt myself, but this time I got away from them, spidering forward into a tiny hole. Where I got stuck. My diving buddies were behind me, and I rapped on my bottle with the hilt of my knife until one of them put a hand on my shoulder. My buddies saw what was up, and attempted to pull me loose, but my bottle and buoyancy-control vest were firmly wedged. The others exchanged hand signals, silently debating the best way to get me loose. Suddenly, I was thrashing and kicking, and then I disappeared into the cave, minus my vest and bottle. I'd apparently attempted to cut through my vest's straps and managed to sever the tube of my regulator. After inhaling a jolt of sea water, I'd thrashed free into the cave, rolling into a monstrous patch of spindly fire-coral. I'd inhaled another lungful of water and kicked madly for a tiny hole in the cave's ceiling, whence my buddies retrieved me shortly thereafter, drowned-blue except for the patchy red welts from the stinging coral. In those days, making a backup was a lot more complicated; the procedure took most of a day, and had to be undertaken at a special clinic. Luckily, I'd had one made just before I left for Cuba, a few weeks earlier. My next-most-recent backup was three years old, dating from the completion of my second symphony. They recovered me from backup and into a force-grown clone at Toronto General. As far as I knew, I'd laid down in the backup clinic one moment and arisen the next. It took most of a year to get over the feeling that the whole world was putting a monstrous joke over on me, that the drowned corpse I'd seen was indeed my own. In my mind, the rebirth was figurative as well as literal -- the missing time was enough that I found myself hard-pressed to socialize with my pre-death friends.
