Right now I start sweating before 0700 and don’t stop till I get home around 2000hrs. It’s extremely hot in those old 18 wheelers with no A/C. It’s so hot in them it actually feels like your walk into an air conditioned room when you get out of them at the field or drying facility. And then throw having to repair or replace a blown out tire and it really gets miserable. I’m really thinking of retiring from helping with farming also. If sweating cleans your pores then mine should be as clean as a brand new shiny penny.
