For some of us this is a KPI of our life/job satisfaction.
I can tell you that if I was in some job that did not allow me to schlep around in hoodies and cargo pants I would be much, much less happy than I am today.
I like working out and being in shape, but if others prefer to do some side project at night instead of hitting weights, it is fine with me. I enjoy reading and thinking, but if others prefer to watch reality tv, who am I to judge them?
Admittedly, seeing some of my middle-aged colleagues who are complete slobs, from their worn-out clothes to their prominent bellies to their unkempt hair and beards and some fun smell coming out of them, is a stress-test for the fortitude of my beliefs.
