Use it or lose it?

I was talking to a delightful fellow student in a botanical illustration class I am taking. This senior woman is one of these "energizer bunny" types that I seem to often meet. She has limitations, but she keeps on going, trying, moving forward. I told her a quote I attributed to my father (I am not completely sure I heard it from him, but I like it): "The less you try to do, the less you can do." A simple statement, but profoundly important to me. I have some physical limitations (bad back, arthritis, achy knees) and emotional ones too (timidity about certain things, though my friends are surprised when I divulge this!). I have trouble digging or turning over soil from a standing position so I either do it in short bursts between other tasks, or I do it from a seated position-looks silly, but gets the job done (and I rarely mind looking silly!). Same with my compost pits- I sit to turn them and empty them. My 86 year old father sits on a low stool to weed, even with surgical pins in his spine. My dear Rosemary gardened in pots until her last spring. As you age into gardening, try to keep doing as much as you can, try new things (within reason), because once you stop, you might never get back to it.
Happy gardening!
