It's been pouring rain here all day today, so I am glad that I went for a swim yesterday at Walden Pond. Was sitting on the wall, reading and soaking up the sunshine, so I got into the water on the late side. The water was quite chilly at first, and the setting Sun was directly in my eyes. So, I kept my eyes aimed downwards, towards the water, or kept them closed when I came up for air. (Whenever I swim with my eyes closed, I wind up unconsciously swimming in the direction of the Sun anyway, so I guess that makes me a Heliotropic organism.)
Once I got close to the back end of the pond, I was in the shadow of the trees, and did not have to look down or keep my eyes closed. But when I turned around and headed back, I realized that it was taking me a long, long time to get out of the shadow. I was in a cosmic race--could I swim faster than the sun was sinking?
