Sorry, I had to get out and work on my self-esteem.

Purely an individual matter, I assure you.

What did I do? I walked down the stairs, out the door around the freeway side of the complex to a blocked-off street that doesn't get plowed, about a third of a mile through almost knee-deep snow, back on the street for almost a mile, looped around a small lake and back the way I came. I ran up the stairs two at a time. All the snow shovelling has apparently got me into shape.

I had a lot of aches and pains when I started. When I got back, they were gone and my legs were pumped.
