I enjoy scuba diving as a hobby.  Have you ever been scuba diving?
Nope never, I get scared of being underwater in the ocean or lakes
Yeah being underwater is often scary.  I prefer to scuba dive in less deep areas.  I really enjoy scuba diving in the Florida Keys.
You know "Scuba" refers to the underwater breathing apparatus?
Self contained underwater breathing apparatus.  The coolest thing I ever seen while scuba diving was a hammerhead shark.
I think the biggest threat is not shark per se but the severe physical stress on the diver
Definitely have to be safe on the way towards the surface.  The "bends" can be deadly.
The most scuba deaths are usually associated with poor gas management, so its mostly human error, you know.
Wow, I wasn't aware.  I'm always very conscience of my air supply while scuba diving.
You can also get alternative sources for air or redundant systems
