I was just going to suggest the Walking for Health groups, NannyJan; I belong to two, and it gets me out of the house. There is at least one every day in the town where I live. I am a lot more active now since I lost DH, as in the last few years he found it very tiring to walk anywhere, so I didn't really bother. One of my walks is about an hour, and the other one we have a choice of a longer or shorter. We have a cup of tea after and it makes it a nice social occasion. It might be worth you trying these, Ellan.
I walked to the hairdressers and back this morning (all of 5 minutes each way!) and I'm about to set off to pick DGDs up from school, about 25 minutes there and back.
