As to the "power of suggestion," I have a huge jasmine vine growing over my tractor shed that I've enjoyed the aroma of for years. I would grab a handful every time I went out to use the tractor. But, a new neighbor brought me a bag of jasmine blooms earlier this Spring from his own Asian jasmine vine, which is a unique variety according to him. Then it came up in conversation, one of Mrs Cosmic's friends told us that she hated jasmine because it smells like mothballs. I thought she was just batty. Mothballs disgust me. But, when I went out to the farm and checked on the blooms, sure enough, all I could smell was mothballs. It smells exactly like something that makes me gag. Now, I gag every time so walk by them. Ha ha, funny how things work like that.
