Great to read your posts about the power of a smile. I also find it to be so true. I am sitting in a café right now and another guest just recently passed me by and gave me a big smile. So uplifting. :)
I've always considered stand up comedians "healers". I think that what they do by making people laugh their faces off (if you can say that in English) is so powerful. I interviewed a stand up comedian once and asked him what he thought he'd be doing if he wasn't a comedian. "I think I'd want to be a doctor and help people. I would like to do something more important than this". I told him I think you already are doing something very important. :)
