Cheers John. It ain't arguing if it's still rational and reasoned. :-) I reckon about the best definition of who you are is how you think, so if you want to get to know someone (or show yourself) then you can't do much better than that...
FWIW, I ain't exactly an expert - I've just been subscribing to NewScientist for a while, so you kind of inhale a bit of background. That just gives a better standard of bullshitting, mainly. ;-)
