Do you know dogs actually do see in color and not black and white? Or how about the fact that your skin is your largest organ? And you probably didn’t know that it would take only one hour if you were to drive up to space. And there’s a lot more where those came from.
There are a few reasons why knowing random facts is a good thing to do. For one, it means you’re broadening your span of knowledge. Learning new things can also help ward off Alzheimer’s disease, by the way. And another reason is to be more of an interesting to talk to!
