I was out walking today. The total time I was out was about an hour and a half, maybe a little bit more. I didn’t actually get that much walking done (although, I walked enough), because I stopped several times to make notes on a problem I’ve been thinking about lately.
Its of the mathematical kind. Its nothing important and someone who does this more regularly would probably come up with a solution pretty quickly, but I still haven’t found one that satisfies me.
