Michael,

When one talks about the null test, you start hearing about submarines, turkeys and "arrogant asses"... people doesn't make a clue what the null test is and why it is a so powerful tool... unfortunately this is not only a British or a Portuguese thing...

But as Tube Dude puted it, HE IS TOO OLD TO CHANGE THE WORLD... and me, I just want to share what makes me happy.
