Yea, for some reason, people think the darkness helps them "get in the zone." I stopped using my HRM because I was sick of trying to press the light button, pressing something else, and then screwing up all of the functions.
I like to be able to see. Last week I heard someone say that they like the dark because no one can see what they are doing .
I despise hats. They make me sweaty and hotter. When did wearing a hat inside become a "thing?" I wipe the sweat away with my hand once in awhile and don't think about it.
