Do you like scuba diving? I always enjoy breathing under water.
I have only done it once, but yes it is exciting! I would love to do it more often to see and explore some cool places.
I prefer the open circuit scuba system due to the discharge.
I could see the benefit in that, the scuba systems all vary in some way or another
I would love to do freedive but I do not need to hunt for food.
Freedive sounds like it would be interesting. Diving can be dangerous though, so safety should be a priority.
Yes you don't want to blackout during a free dive. You must always protect your cerebral hypoxia.
