I was discussing this with Judy. She shook hands with President Bill Clinton once and was surprised how hot and damp and flabby he was. She admires Clinton and thinks his hand may have been hurting from over-use but I'm not convinced.
None of us knows what its like to be on the receiving end of our handshake- which makes it very hard for us to control the message it sends. Is a handshake a reliable indication of a person's character? I have to say- fair or unfair- I take it as such.
