This morning I took Maarten and his best friend Bas to the NEMO Science Center in Amsterdam.

We had a great time exploring and taking part in all of the scientific experiments, and although this place is geared towards young children, it was also refreshing knowledge for pseudo-geek parents like myself.

There was also some exhibition on the brain and how personalities define who we are.

I sat down behind one of the computer terminals and did the 10-minute quiz consisting of forty odd multiple-choice questions.

Finally arriving at somewhere in the high thirties, the poor computer got so confused by my answers that it froze with the following last gasp message:

"Syntax error, index out of range."
