This makes a lot of sense! I used to swim a couple of days a week and run, and even participated in a sprint triathlon, which was loads of fun. I think this lethargy started when the exercise stopped, come to think of it. I do walk, but it’s not the same as the aerobic I used to do. Your post is inspiring. I think I need to get back in the pool, which was something I enjoyed, until everything just seemed to be too much effort. But you’re right; I have to start somewhere. Thank you.
