We get it. It's cold.

You're probably sick of hearing all about just how cold it is in the Midwest and other areas of the country. A polar vortex has come down from the Arctic for its 15 minutes (days?) of fame and has dominated headlines.

Stop me if you've heard these numbers before, but Chicago felt like -50°F with its wind chill and had to light its train tracks on fire to keep them from breaking in the cold. Lake Michigan is almost completely frozen over.

The postal service has canceled mail delivery and many school boards have also suspended classes until the weather warms up.

There are some people who can't cancel their jobs though and thousands of Americans are bracing the dangerous cold to do their jobs every day.

Police, paramedics and firefighters can't stay inside just because they're cold. They have to brave the weather while doing their already dangerous jobs. Some have managed to still have some fun with it. The McClean Police Department "arrested" Elsa, the Disney princess from Frozen, for bringing the polar vortex down.

Not all departments have been having as much fun however.

Fire Chief Mitch Hansen is one of those. He's a firefighter with the Cameron Fire Department in Wisconsin. That state has been one of the hardest hit by the weather with temperatures well below -30°F.

ABC posted a picture of the now viral first responder after his beard had frozen while fighting a fire. The firefighters battling the blaze said that the over-spray from their hoses was bouncing back and hitting them as ice pellets. That means the droplets were freezing almost immediately.

The incredible picture is a reminder that the cold weather is more than just annoying. It's dangerous for all the men and women who must go out and brace it.

Thank you first responders and everyone who is still keeping the country running!
