Hey, I've always noticed the trend that life is more like a curve than a straight, upward line. I think you hit that peak around your golden age of 50, and then head back on a decline. Considering that living to 90-100 is normal these days, people 75 or so are about back to the level of a teenager, aren't they? Time to institute permits.
I tell you what, if I can't shit in the toilet, I can't drive.
