Ah, but almost everyone's sending deteriorates with age. And, it's not easy learning to switch to paddles (or play the piano or learn a language) if you are elderly. Lots of guys you hear using bugs whose fists swing are doing their level best. I will say I'm fighting it as well as I can. I frequently practice both QRQ and QRS sending (yes, QRS. I lost the ability to send slower than about 13 WPM, and I had to work hard to get it back. In fact, it's still a work in progress).
