So true. Back in the 70's and 80's it was 2 a days and I don't remember but 2 people getting over heated. Probably because we weren't the couch potatoes that the kids are now days. From the time we could get out we stayed out from day light to dark running, playing army, riding bikes, playing pick up games, wrestling, fighting or whatever. But at the end of the day we were all still friends and went home planning and waiting for the next day. It was called being aclimated to the weather. Hot or cold.
