Good comments....and agree....when you get on this site you realize how many people really know their stuff and across a wide spectrum of this subject....i could spend a week trying to think of something original but my interest has been HRT....and this site has given me more info than the specialists and GP's combined.....and i believe source checking is one of the most responsible tasks any person could undertake.....but so is becoming intimately familiar with the subject....good thread mate
