Hmmm. Yes. A real problem.

I guess we could all take up texturing as a hobby (there can never be enough royalty free high resolution textures). Grab a camera (even an iPhone), go outside for a walk, and start photographing the textures of everything you see. If it's cloudy, with diffuse light, you can probably photograph almost anything because the shadows and highlights will be very soft. It it's sunny, or there are shadows and too much highlight, look for things that are in the shade.

If nothing else, it gets you moving, bending, squatting, leaning, crouching, and standing on tiptoe. All low intensity, but very useful exercises, especially as we get older and older. And it'll improve your photographic skills immeasurably.
