My sister conned me into wearing it a few years ago. Some crackpot suggests I was 'surrounded by a cloud of darkness' reckoned she was a clairvoyant. I thought it was fair to my sister. I had needles up my arm at 16 and she is nearly 3 years my junior, getting knocks on the window at random times on random days because mum deadbolted the door. According to this clairvoyant, I needed a crucifix or an exorcism! 
Anyway, I put the thing on and it works well. Good conversation starter. People think I am wierd but no change there.
