My wife and I like to go scuba diving. Breathing underwater and relying on the breathing apparatus makes me a bit nervous, but it's so worth it
I have never been scuba diving, is it hard or complicated? Do you use oxygen?
Yah the compressed air is the SCUBA (self contained underwater breathing apparatus). You have to take courses before you can do it safely
Do you scuba dive commercially or recreationally?
Oh only recreationally. We go with guides. People have been diving underwater for ages, even in weird diving bells that trapped air from the surface in with you
Really? what else can you tell me about the history of scuba diving?
Well, it started with freediving as a means to get food and other resources like pearls and coral. The greeks and romans had commercial freediving enterprizes
Oh that is very interesting, is it dangerous or are there any hazards to watch out for?
