Oh, yeah, I forget to say, that I actually ... I would have lasted underneath half- full-breath state underneath water for about one to three minutes more ... when I finally floated up to water surface ... I'll never forget that moment, because I thought I was going to drown (I was only nine, ten years old) ... but now that I think of it, I could have lasted another one to three minutes without drowning myself with water into my lungs (I was holding my breath and I was fully conscious. I could have lasted another one to three minutes holding my breath underneath water without inhaling even if I were half-conscious. But after that ... you'd drown. a.k.a. you inhale water, turn unconscious, and sink down until you land at the bottom of the 100 meter depth adult diving pool.)
