Hey everyone. I was just singing along with the radio... like always... and had a bit of an epiphany i wanted to weigh against everyones experience. I recall reading "Freediving" by Umberto Pelizzari and there were a lot of soft palette exercises moving your tongue in different ways and making different "ah" and "Ooo" sounds that scared the life out of my dog... anyways i was wondering if there is a correlation and/or effect between singing and freediving/spearfishing.. being that i am a practiced vocalist and many other spearos i know are avid singers... drunken karaoke at least.... what do you think?
