I agree NBB,,,,,it has been a burr in my backside since 2013 everytime I think about it!!,,counting data that taints results,,,we went thru that discussion here a few months ago and it still is sort of a head scratcher!!!

but,,,PC in regards to your post...as far as post hoc analysis goes,,remember you old guys would never have had the bennefit of Viagra with out it!!!..think about that for a moment,,,,while..speaking for myself only, I dont need it,,cuz I change ladies here in the seniors home every few months,,,, :o)
