Before I retired, I used to take a half-hour walk at lunchtimes, to clear my head, breathe the fresh air and take in the sea views, while getting my body working harder. It broke up the day, was a great stress reliever and gave a pleasant sense of well-being. Nowadays, I like to do that walk, still- but also enjoy the local forests and hills. Two or three times a week seems about right. I'm lucky, that I can get up into the woods behind my house easily, during current restrictions- and usually see no-one, if I'm up there for an hour or two. At this time of the year, I would normally be looking forward to my first mountain walk of the spring, once the kids were back in school and my favourite spots became as empty as a politician's promise. It must be murder, for active folks, who live in high density housing developments- but at least the road traffic is way down, so the city streets and parks have cleaner air.
