What a load of irelevant cobblers! People call this thing a valve, a tube, a
bottle, or whatever, because that's what they were taught to call it. Nine
times out of ten they never even begin to think about "why" it's called what
it's called.

After the complete load of twaddle that was your last post you certainly do
seem to have a knack for talking total bull****. :-)

David - it's called "psychology". You may have heard of it at some
point in your life. I'm a psychologist, I teach Performance Psychology
at MA level at one of the London universities, I have published 4
books on psychology, two being textbooks. I have appeared over 80
times on TV and Radio talking about various aspects of performance and
media psychology, including several appearances on the BBC News.

It should be fairly obvious to you that I'm well known and respected
in my particular field.

You're welcome to call psychology "twaddle" - that's your problem.

So do tell us what have you done in your own life that raises you
above the level of "twaddle"?

You seem to think you're "above" all this and no doubt inside your own
head you feel superior. Do you have any concrete evidence of your
superior thinking or is it just a self gratifying perception?
