I grew up breath holding eyes open no mask, after some years got a mask, later got a snorkel wow it was magnificent.
I even hammered a three inch nail into my mothers mopstick, when she was not looking, cut a couple of barbs in and caught a flounder, and even though I was surrounded by fish catchers, I knew realised fish catching wasn't in my nature. When I finally got some fins it was magnificenter and then came years of praying for a tank so I could stay under for just a while laying on the bottom on my back or my front or on my side longer than a breath hold
and then I became a teenager
I always have plenty of air planned in my plans and then some more so I never ever will need after years of using one, and sick to death of them, and finding absolutely no reason ever for ever using one in scuba diving, to carry use, to rescue, look at fish, wave in the air, hit other divers, cpr, pass to other divers to tow them somewhere, trap my head in a crevice, find my way back, rescue myself, poke myself in the head, tangle my hair or conserve my air no stinking snorkel
