It's like an alarm clock

A guy I work with told me "I always set my alarm early enough that I can get to work before it's nine-
-ty degrees outside."

Walking down those last 2 blocks from the metro station with the sun beating down on my back, when the day isn't old enough for the air to have dried out from the morning dew so the humidity is even higher than the 99% I usually deal with, I continually try to find the perfect speed that will allow me to get out of the sun as soon as possible while generating a slight breeze, but not so fast that I actually have to exert myself and start sweating - because god knows the moisture that is condensating on my body right out of the air is enough without me contributing my own juices.
