The other night we were out walking the dog when the sudden urge struck to spin around in circles. You know how that just hits you out of the blue? No reason at all? Certainly not the wine I'd had earlier, I'm sure that couldn't be the reason.
So I stuck out my arms and span around a few times, got dizzy and grabbed onto DrH for support. To which he very soberly said:
"Well that's what happens when you have a drink and then rotate quickly around your vertical axis."
