You've come to the right place. It's just that I couldn't read it at first although i can read Latin. and then looked it up. Took a while as I tried it word by word. I you google it its easy. You'll find (just one of many explanations) that the Harvard foorball boys used it. You living in the UK made me wonder. That's all. And no you don't need a degree. Being crazy should do the job as:
1) It will cost you a small fortune
2) A helluva lot more work is involved in preparation and maintenance
3) It's beleived to be more dangerous
4) Your OC buddies will refuse to dive with you as you only have interest for your equipment.
And the list goes on.
