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
