The cold weather is making you bitchy, says science:
No kidding! Below zero makes a person outright swearing, pissed off. You hop up and down and flap your arms across the chest and try hard as hell to find some warm place to run. It is more interesting than that, it also makes a person think harder and do saner things. People who do dumb things when it is bitterly cold, die. I work a lot in severe cold and can attest to this fact. You become very organized and focused on finishing the task as quickly as possible. Mainly, shoveling snow or repairing something or going somewhere.
