Just caught an item on our local news re: Swimming for Dementia (soon to begin in 6 London Boroughs). Evidently swimming helps cognitive functioning. The woman from the government was "passionate" (twice) about this initiative. They chose to stand by a pool where people were going up and down in lanes. Didn't tempt me. A smallish warm pool with some floats, balls etc. would be fun. Husband trying to understand changing room lockers would not. I await the roll-out of this initiative with interest.
