People who work outside generally do not do it in bare skin unless they are idiots (of which we have many, many, many examples). You don't typically see military folks wearing shorts and t-shirts even in the hottest weather unless they are out doing PT because the work they do can be harmful and so they use clothing to protect themselves. This used to be common sense. Why do bedouins wear long, flowing robes in the desert? Same reason. My father, who worked outdoors most of his life, always wore long pants and long sleeves even on the hottest summer days. I did not understand why when I was younger. I now get it.
