Light Bars

Long day of work today. I'm very weak willed at the moment, again failed to force myself out of bed for a run. Needs to be addressed. Writing about the evolution of warning colours at the moment, which is reasonably diverting, although not as fascinating as the lecture I had on insect vision this morning (I won't bore you with details). Autumn is progressing steadily, the leafblowers are making neat brown piles beneath near bare trees.

Bye Barbara
