Yes, I have. I considered converting to Buddhism from Christianity about a year ago. It would have been funny to see all of my familys reaction because I confided in my sister that I was thinking about it and her respond was basically: Uh...what? Hang on, let me get this straight: blahblahblah...

Nope. Not in the least. My friends feel the need to Chlorox stuff for the tiniest of reasons and to be honest  it really seriously annoys me.
If I do, I think my immune system can handle it - I almost never get really, really sick.
