Wispy clouds over St Mary's Cathedral

I managed to pull a back muscle at work today. It wouldn't have been so bad if I was lifting heavy weights or something, but I was just fetching my towel after my lunchtime jog. My wife said this was just a sign of advancing years, and we should all just (somehow) be "more careful".

As a consequence, I had to half walk, half cycle my way back home. Which wasn't so bad as it was a lovely evening and I was enjoying the beautiful light. Then my bike fell on me and scraped one of my shins, while I stopped to take this picture. Fortunately, I still like those wispy cirrus clouds so it was worth the additional injury.
