Today on something you should know, Christmas is the favorite holiday of many, but it used to be illegal to celebrate it.

I'll explain when and why. Then your voice. People make assumptions about you by how you talk.

When we talk in a low pitch and in vocal fry and maybe not with a lot of pitch inflection like I'm talking now, the perception is negative that we're tense, that we're weak, that we're hesitant.

Also, does it really help to write the word fragile on the Christmas package you're sending? And our connection with animals, interacting with them has an amazing effect on us.

What we do know is that domestic animals increase our lifespan. Owning a dog will improve all kinds of things from your heart rate to your stressed level, and even potentially how long you live.

But did you know that celebrating Christmas used to be illegal? By the time the Puritan settled Boston celebrating Christmas was outlawed.

In fact, from 1659 to 1681, anyone caught making Mary would face a fine for celebrating the once pagan holiday.

After the Revolutionary War, the new Congress found the day so unimportant that they even held their first session on December 25, 1789.
