So tell us...when the day comes (and it will) that you can't ride anymore, or ride where you want or as much as you want, will you just give up? Will you let go something that has been an important part of your life just because as humans we fall apart as we age? Maybe your joints and parts will be fine until you're 80 or 85, one of the lucky ones, but eventually your body will fail you. I see absolutely nothing wrong with using technology to allow you to continue an avocation you love. It can enrich your life. Or, you can stay narrow-minded and quit things as your body quits.
