Most folks have never had to work outside, let alone work outside when the temperature is below zero and the wind is howling. It's down right dangerous for those not prepared, and miserable for those that are prepared performing necessary tasks in extremely cold weather.
As an phone repairman, I spent everyday outside in the elements, but only a very few in extreme cold. I have the utmost respect for those that can't escape their job when the weather turns brutally cold. Utility workers are the first that come to mind. When the power goes out, or a water main breaks during cold weather, somebody has to fix it.
Fire fighters and other emergency personnel don't catch a break either. Their jobs become so much more difficult and dangerous as the temperature drops. When you get in trouble who do you call? 9-1-1 and some how, some way, someone will show up and help you no matter what the weather.
Ag workers obviously don't catch a break either when it gets cold. Livestock needs attention, especially when the temperature drops, and it only takes a half second of observation to see who is dressed to work outside and who isn't. When the livestock needs help the most, it is always under the most difficult of conditions, often in isolated locations. I don't envy ranchers and farmers this time of year!
So as you cuss your car for not starting, your glasses for fogging up, the ice you just slipped on, or the price of your utility bill during this cold weather, don't forget to thank the folks that do the outside jobs so the rest of us can remain insulated from winters harsh reality.
