And yet more and more people are doing it. Why people why?!?! Listen, we weren’t meant to be underwater. The fact that our cell walls start to explode and oxygen levels deplete in a few minutes should be half a clue that mother nature didn’t design us to be here. Then again, nature didn’t design us to fly nor sit at the computer blogging all day so I digress. If you love free diving, then you may need the D-eepdive gadget.
