I am fast running out of ways to keep fit. My years of running were stopped by knee problems. My three decades of lap swimming ended with shoulder injuries which only surgery might repair. And my walking career has been constantly thwarted by both knee and foot problems which will not get any better.
I could take up cycling again, though likely with another e-bike. I do have a tendency to fall off from time to time so spectacles will be necessary. To stop more falls, need it be said.
