Unless your bouyancy control is so bad you shouldnt be in the water, what does it really matter?
Ive been at walls that just keep going into the blue and its really not as bad when youre there as it is thinking about it
I have to agree with him. As a kid I would swim in waters 100+ feet deep and just to think about what could be going on below you is fun - a bit scary. Just to think about it, it is a mental thing. Imagine being a mile up in the air! How many whales or giant squid could be just below you Or Giant lobsters...
The divers going to 250 feet and getting narced and running out of air is worse, though. That really scares me.
