Sometimes when it gets cold enough I think I get in a bad enough mood that my body temp goes up a few degrees. I rode in to work today with a real fire in the belly so to speak.
It's easy to be in a shitty mood when your kid is sick and you're not sleeping. Throw in temperatures in the low teens and that's pretty much a blueprint for one of my worst-case scenarios. Mid-afternoon meetings? Even better.
Current beer-scale: 9.2 if only I can make it until dinner.
