I detested each and every one, loathed being made to play with a passion. I was awful at all of them and hated everything associated with them. However, short of a hailstorm we were expected to play for 2 hours 5 days a week and watch the school teams playing at home on Saturday afternoons as well. We also had PE for 2 hours a week and athletics in the summer too.
The minute I had the option to give up I did so and aside from the odd bit of skiing and regular shooting I have never been near a sports field in the 30 or so years since.
I avoid all televised sports and genuinely managed not to see a single moment of the RWC or the Olympics.
So for me, if the kids want to do it then fine, but for some it is tantamount to waterboarding!
Mind you, I have no kids so my opinion is theoretical at best.
