So tell me more about scuba diving!
Well scuba diving is a blast first off.  Scuba divers bring their own equipment so they can breath underwater.  The advantage of course is getting to explore more of our oceans!
When did it start?
It didn't start until the 1940s so I always imagine how crazy under the water was before humans got there.
LOL it sounds really fun! Has the technology advanced since the 40s?
Yes, it has advanced quite a bit with different breathing machines available.  They even have machines that will use your own gases recycled!
That's amazing! Are there any other fun facts you want to share?
A lot of people can't scuba dive because they can't handle the mental side of it and that is why it is important to get certified and make sure you can do it before just heading out to the ocean.  It scared me a little bit at first.
I bet it did! all of the sharks!!!!!
Of course sharks are scary but I never saw one and I bet most people never do even though they have been around at least 420 million years!
