I agree with Bumble and Bertrand and think Ive probably read the same research as them too. You're far more likely to drown as a swimmer than a non swimmer, because you're more likely to take risks and get yourself into situations that you can't get out of, and so drown. Like those who swim and drown in the local quarries etc..
Neither My husband, father* nor my grandfather could swim. And none of them drowned, because they never really went near water. So, it has never been an issue that has affected their lives. As a swimmer, I think DH has missed out... but as DH points out, he never learnt to swim because he never liked swimming, so he's not missing out on something he's always hated doing. I kind of get his point. I can't play tennis,do I think I'm missing out? No because I don't enjoy tennis and so don't want to learn. I can see where he is coming from.
So yes, we have holidays in hotels with a pool but DH doesn't really swim, he'll paddle but wouldn't go out far because he doesn't like it.
I think if your son can be talked round with 1:1 lessons, then swimming is great, but it's not something I would force. Many people never learn to swim and in the UK, it's fine so long as he's sensible with the risks. He can always learn when he's older. My dad eventually learnt to swim when he was in his sixties. He still doesn't like it though, and so never goes....
