Thanks for your replies Caro & Jodi - so quick, too! I was pretty sure it was a wives-tale, and it sounds like I may have been right. Didn't stop me from starting to doubt myself though! Thanks again, Smelly.
p.s. - Caro - username is actually a nickname that started when I was a child. Not because I stank, but because it rhymed with my name and kids like to find any way of teasing. Weird thing is, I'm kind of fond of it now!
