Shouldn't a video disc be called a VD instead of a DVD?

I think calling it VD might be considered bad marketing (although that may depend upon the market sector, but most family men might have their wives look askance at them if the suggested they were going out to get some VD).

More seriously, DVD originally meant Digital Video Disk, but some people now prefer Digital Versatile Disk because they like to emphasise that it is used for more than just video, although most people still think of it as Digital Video Disk.

there are sacks of fluid in each joint of your body and preassure can build asymetricaly in them if the force applied to the cartalidge the crack is the equlisation of the pressure.

i dont think ive explained that very well try this, half fill a balloon with air(replacing the fluid sack) now using your fingers pinch in the middle now play with it see how the balloon wants to maintain equal pressure in both sides and will rush from a high to low pressure side if given the chance thats exactly whats happening in your knuckles.

J.B.S Haldane on the perforated eardrums which were a consequence of his pressure experiments "the drum generally heals up; and if a hole remains in it, although one is somewhat deaf, one can blow tobacco smoke out of  the ear in question, which is a social accomplishment".

Unlikely, since the key is already in your hand, and any radiation travelling through your chin could just as easily travel up your arm.

I would suggest you test whether you car key, at chin height, but well away from your actual chin, works as well?  It may well just be the height above the ground (and clearance from other obstacles)  that is the key feature.

There was a saying that my mother used to say from when she was in the Israeli army and army cannot be full of generals in other words, there is no point in having leaders unless you have a substantial number of followers.  In any group of people, there will always be a few leaders  and many followers.  If there were no leaders, or if everyone tried to be a leader, there would simply be anarchy.

4getmenot...what exactly do you mean here?  I agree with George on his standpoint here..and in order to be a good leader, one must be a good follower...hmmmm, just some food for thought...but please expound if this is not what you are talking about...are there examples that you could share about leaders that you think they are more or less followers??

I was told earlier this week that I was a follower,I didn't think too much about it but I hope it wasn't meant as a criticism.

Love you lots.

OK, to clarify a little of what I meant.

To me, a leader is one who takes responsibility, and provides direction for others.

Firstly, if there are no others, then who does he lead?

Secondly, it must also be remembered that a leader also serves those he leads, and if those who follow his decide he is no longer leading them where they wish to go, then the leaders services can be disposed of.  In fact, leadership is a very volatile position, and most leaders have a very short time in the role of leader.

Leadership is also contextual.  A ship's captain may lead a crew while he is aboard his vessel, and yet on land he may serve others.
