Hello! Hope you're having a great day, I'm looking at videos of underwater diving! 
how fun! It's so cool to be able to descend below the water's surface to interact with the environment
Yes! I agree so much, I would love to go underwater diving, have you been?
not yet. You see humans are not physiologically and anatomically well adapted to the conditions of diving so i'm a little bit scared
I'm a bit scared as well, that's why I'm looking up videos so I can learn more. :)
lol i would rather watch videos :) the diver is directly exposed to the pressure of the surrounding water 
I'll watch videos for a long while until I'll ever be comfortable ha!
you should know that the environment exposes the diver to a wide range of hazzards!
Thank you for the warning, I will prepare myself for that. I'm most interested in seeing how the oxygen exchange works in the mask.
some divers actually just dive on breath-hold. i would definitely drown without breathing apparatus
