I learnt to swim in my forties but never got to beyond a child's pool. The trainer did do his best to get me take long laps but for whatever reason I just could not. I finally gave up. I had a choking experience and that could be the reason why I lost courage.
Are you a good swimmer?
I don't know how to swim. I never learned it. I could only wade in the pool or sit and watch others swim hehe
