Well,there you go,Acorn4 !! Me too---I learned to hate rugby( we weren't allowed to mention football) and yet seek refuge in cross-country running.My fellow ruggerphobes and I were not as dedicated as you,though---we used to run about a mile,then stop in the woods,light a fire,and have a smoke !
             On a serious note, I think that one of the most useful things for me,from my Primary (Junior) School days,was my learning of the "Times Tables".Young people,who are not taught that sort of thing in the UK any more,are always impressed when they say,for example, " What's nine times nine?" and ,quick as a flash,I reply " Eighty one !!" and they say " How did you DO that?". How sad !!
