Don't freak out at this map on infectious diseases in the world. It's good stuff to know.

We've figured out a lot of things over the years, like how to use hashtags and why we should recycle. And way more seriously, how to fight off some of the world's most horrible diseases. For all the progress we've made on that last one, these maps clearly show that we have more work to do.

*A note from GlobalPost on how these maps are set up: The numbers in black boxes show how many thousands of people died from the dominant infectious disease in that country in 2012. Keep in mind that these are absolute numbers, so they're not scaled to account for a country's population. (You can find population numbers here.) They also don't convey the total number of deaths from all infectious diseases in each country, just the number of deaths from the deadliest disease. You'll also notice that many countries in the maps are grayed out (like the USA). That indicates the deadliest infectious disease wasn't among the ones monitored by the WHO.

Those maps are pretty hard to look at, but the state of deadly diseases isn't entirely bad.

Take the evilness known as malaria, for example. We're on our way to getting rid of it for good! Check this out:

One of the strangest things about being human is that people of lesser intelligence tend to overestimate how smart they are and people who are highly intelligent tend to underestimate how smart they are.

This is called the Dunning-Kruger effect and it’s proven every time you log onto Facebook and see someone from high school who thinks they know more about vaccines than a doctor.

The interesting thing is that even though people are poor judges of their own smarts, we’ve evolved to be pretty good at judging the intelligence of others.

“Such findings imply that, in order to be adaptive, first impressions of personality or social characteristics should be accurate,” a study published in the journal Intelligence says. “There is accumulating evidence that this is indeed the case—at least to some extent—for traits such as intelligence extraversion, conscientiousness, openness, and narcissism, and even for characteristics such as sexual orientation, political ideology, or antigay prejudice.”

'Merry Christmas' on YouTube.

The world must have been—mostly—good this year. Because Elton John and Ed Sheeran have teamed up to gift us all with a brand new Christmas single.

The song, aptly named “Merry Christmas,” is a perfect blend of silly and sweet that’s cheery, bright and just a touch bizarre.

Created with the holiday spirit in every way, it has whimsical snowball fights, snow angels (basically all the snow things), festive sweaters, iconic throwbacks and twinkling lights galore. Plus all profits from the tune are dedicated to two charities: the Ed Sheeran Suffolk Music Foundation and the Elton John AIDS Foundation.

I personally don’t know which is more of a highlight: Ed Sheeran channeling his inner-Mariah, performing a faux sexy dance in a leg revealing Santa outfit, or him flying through the air with a giant Frosty the Snowman … who seems to be sporting glasses similar to Elton’s. Are we meant to believe that Elton is the Snowman? This music video even has mystery.
