Anti-sweat math

Sevilla was strikingly cool today. Cool enough to walk on the sunny side of the street. That has not been possible since... early May, perhaps? It was still probably about 30 degrees. Maybe 28 or something.

Normally, as heat loving as I am, I take the absolute shortest route possible to any scrap of shade. Walking along a narrow street, if you want to walk on the other side you would cross diagonally (there is only room for 1 car going slowly, there is no such thing as j-walking, and you have to cross, many times, because the sidewalk - whose width varies - is too narrow for the car to pass safely, besides there are no proper corners from which you would or should make your crossing). So you walk diagonally continuing in roughly the same direction, so you don't needlessly waste steps. If you were intending to go straight, you would not walk at a 90 degree angle for a few steps and then continue straight. Nobody walks in a perfect square or even a backwards diagonal, unnecessarily. What I'm trying to say is that the absolute necessity of getting your body into shade makes me do that here. I never knew what a B-line really meant (I mean from experience. The term seemed kind of useless before).

Fine, I have to cross bridges sometimes in full sun. If you have to do it, you do it. I am used to sweating. Here, it is different. You don't freak out about a little sweat. But you really don't want to end up dripping if you can avoid it, and if 3 steps at a 90 degree angle to your path get you into the shade faster than 5 steps at a 60 degree angle, that is probably half a second difference, but I am going to take advantage of it!
