Last night, I did the first rather strenuous workout I’ve had in…well, let’s just say it’s been quite some time. I went to the fitness center our property has set up and did 8 miles on the stationary bike (in under 30 minutes, I should point out) and then walked for 15 minutes. My knees are, to put it mildly, not happy. At all. That I can walk today is a miracle in and of itself.
