carebear, forgive my ignorance but what do you mean by a sensitizer...people are sensitive to them?...oh by the way i love" you can't cure stupid"....it is something it has taken me about 50 years to finally realize....now i don't have to continue having long and frustrating conversations anymore....I used to think that with just the right words and careful explinations....folks would understand simple truths....I now keep my opinions to myself...mostly....I.have a lot more spare time these days!
