I've never actually seen one with sweat dripping down it's forehead but I can tell you they control body heat by a number of ways:
1. Taking frequent baths and not completely drying off their feathers after a swim.
2. Sitting in the shade.
3. Drinking plenty of water on a hot day.
4. Plucking down from their bodies during a hot spell.
I did see one goose almost pass out from heat exhaustion, but luckly his buddies got him into the water just in time.
"No sweat" is something people say in two circumstances: "Was the exam difficult?" "It was no sweat." (It was easy.) "Could you help me with this?" "No sweat" (I'd be glad to.)

You could wear sweat pants on a hot day to sweat more and when you sweat more you lose more weight. But wearing sweat pants on a hot day is not good for your hygeine. You could pass out while you are running or doing a sport in PE. You could get dizzy because your so hot and you fall down. So what i would recommend is to wear shorts so you can be more active and have a better hygeine.
No, I don't think so. If they could sweat then they'd be drinking a heck of a lot of water. Most European cattle don't have the sweat glands in their skin like the Brahman-type cattle do. However they can sweat through their noses, as you often see beads of water on their noses when it is warm out.
it could be 'sweat' or 'raw' x
Could be caused by not wiping enough, sweat, or itchy undies.
