I took this during a rest-pause between sets of toe exercises. Never thought of there being such a thing, and now they’re my thing. The hardest one isn’t the up or down or splay, but to concentrate on moving one toe at a time. Of course, the whole set comes along, but it’s important and productive to concentrate on one toe at a time in sequence. By thinking it, the part of the brain that controls the action is stimulated, and this hastens the recovery.
You can also see the wrinkles I have accumulated. If I hang the foot down or put it on the floor for five minutes, they won’t be wrinkles any more as the blood re-inhabits the foot. It also gets flushed a vague rosy purple.
