Maybe because I seem to have a high immune system but those rarely do much for me? Now those damn pens or ( whatever they are called ) will put me on my ass. I was at a female friends house ( one who I liked ) and her dad, sister, brother ( First time I met them ) was over and the dad got me to try it. I about ran out of that house. I know my stupid mouth. I was fubared. They giggled thier ass off as I choked on it. Never again. Atleast not in that situation. Lol
