On Habit and Self Reliance
I learnt to dive the PADI way, safe in the knowledge that my "buddy" would be there to help if I needed them. So if I was struggling to get my fins on they'd steady me, if I got caught in some fishing line they'd untangle me, and in the unlikely event that I ran out of air, we could breath from the same source. The "buddy system" provides a great comfort blanket and makes recreational diving that much safer.
