I was a widower for three years when I decided to take some yoga classes, good for body and soul (soulcializing too?), and after one class, (I looked it up, 13 years ago to the day!) there was a Zumba class, so I stayed, and danced and gyrated with the rest of them, trying not to look like a slow old man, when, pop, a searing pain unexpectedly had me suddenly swaying slowly, practically giving up but not wanting to look like a quitter. Shuffling out I realized it was a hernia in the groin, most unpleasant. Repaired, of course, but also subdued. (‘sup, dude?) Curtailed my yoga and never Zumba’d again. Might try tai chi, which I truly enjoyed decades before. Well, your calf story brought it all back, the indignities we experience with age are truly humbling.
