Just a quick message now. I've recently started scuba diving, which is great fun. So far, I'm very much a beginner, and it's strange being on the receiving end of teaching! I've got a textbook, homework, and even an exam this weekend! So far, I've spent a day doing the confined water dives (in a swimming pool), just getting used to how all the gear works, how to get “neutrally buoyant” (so that I neither float, not sink like a stone - not easy!) and so on. I've also spent one day at sea, and did my first open water...
