@HebrideanHecate @Maud_Gonner You might be amused at the graduation requirements in California high schools in the 1960s: you had to learn to swim. Of the three gym class offerings I had in Riverside in 1969 I chose tennis; the other options were modern dance and touch football.

I miss swimming so much, preferably in Maine's innumerable lakes and ponds, but with an open wound from butchery (surgery) I can't take a chance on picking up flesh-eating bacteria.
