Well. At that time I found hold my breath for 20 secs max. I was at my swimming lessons, I had to swim from one side of the pool. I did. Apparently I was there for about five mins and I went real deep, everyone was calling my name. I was under there oblivious to it, counting how long it took me. I counted 7 seconds, apparently it was five minutes. Plus I could feel air on my back? I kept on accidentally diving too deep that I actually got kicked out..
