Old guy exercise
Getting reasonable exercise with as many worn out parts as I have is not an easy task, so I rely on our Personal Trainer - Fritzie the dog. Getting past 75 has been a lot less troublesome with a couple daily dog walks. Dogs are perpetual 3-year-old children - they want to be outside doing stuff, need to stop and examine everything (which slows down the action to a doable level) and leads to pleasant interaction with other dog walkers. Best of all, unless you're in a big city, not even Covid interfers with your daily workout, and in the winter, wearing a mask is both a way to stay safe from the virus AND be kind to your lungs in the northern climes.
