I offered advice on email to a man who had a bad sunburn. To his credit, he was open-minded enough to try what was recommended from a woman with whom he was chatting as part of an internet dating process. I told him to palm his calves. One does this by crossing one’s hands and placing a palm on each calf, holding that position for about 15 minutes. He followed  the instructions. Next day I got the word: his burn was very much better; the heat had gone out of it. That man was impressed and a lot cooler!
