Big Dog - 'totally yammering' - have I touched a nerve? Not at all, I just get a kick out of listening to people pontificate. I have plenty of clients that are doctors who love to expound on the science of medicine, until the latest discovery comes along and they have to reverse themselves. Oh, yes, ahem, er, we used to believe that but now we KNOW it to be thus. I just find it humorous at how little we really know about anything. I was in a surgeon's office the other day and I picked up some materials left by a drug rep, way down at the end in the fine print it said that the drug company wasn't sure exactly how the drug did what it did and so on. I find the science fantatics as funny as the religious fanatics because really by the geological clock we have barely swung down from the trees and we really know next to nothing about how the universe works.
