Taking a week off work (and there was much rejoicing!)

Can you produce a pie chart at the end of it of how your time was divided?

I am willing to place good money on sleep being the biggest slice, and DIY playing a significant role too.

Of course, this depends on how you devise your categories. If it is just "sleep" and "not sleep", then I'm predicting "not sleep" may win - perhaps occupying about two thirds of the resulting graph.

OK John, I'll try and keep a log.

Isn't there an important principle in physics that states you can't measure anything without affecting it?

If you keep a log, then surely that activity in itself will take time, and thus will have its own slice of the pie chart, and knock all the others off skew. The credibility of the whole experiment will be called into question.

I suggest instead that you just make the results up, preferably the night before the deadline.

Or copy them off Jon Ellis.

Sounds like a plan John. Cheers for that.
