>>392700Freediving, probably the most relaxing extreme sport, also one of the most dangerous. I personally get off on the rush of going into the deep dark depths spearfishing and going under rock ledges and kelp beds.
No shark threat where I live, but the occasional seal gives you a scare. The only real danger is staying under too long and blacking out, which is something I have experienced, luckily in a pool practicing.
And other freediving sc/out/s on?
