OK, this is a bit random! But cutting up an orange yesterday I wondered why children and adults playing football always had a quarter of orange at half-time. Whilst certainly good for you I could not see a quarter of an orange doing much to enhance performance! The internet suggested that colds were more prevalent in winter, but I think the clue is more to do with the date of introduction – 1950’s – post-rationing? Even then it still seems a little strange? Why not a piece of chocolate or piece of a banana?
