"strain on the elbows. I want to know why." (IE)...look at all the strapping and bulged veins on the ladies tour:
Tennis is a very masculine game, and the more masculine someone becomes by hitting lots of balls, and doing weights, the better they will be - unless they begin to get the injuries. Table tennis, on the other hand, if you'll pardon the pun, is much more about reflex, and the very top female players can keep their femininity - you may have noticed this during the olympics. I want to add, as I did on the still alive "Anyone for tennis?" thread, that I'd be quite happy, though, to work as a production manager under a female MD, or for the next Archbishop of Canterbury to be a female. However, if on a shop-floor I noticed a female about to lift a 25kg of raw material, I'd stop her and do it myself.
I've also admitted that pro female tennis players probably would beat me with my clubfoot and relatively slow court speed - but that is not the point, if you'll pardon another pun.
