Why is a reflection in a mirror that's right in front of you just as blurry without glasses on as if you were really looking at the same thing far away without the mirror? | [
"A mirror preserves angles as the light is reflected, so the light reaching your eyes is just the same as if object was behind the mirror [like this](_URL_0_). If your eye couldn't focus the light coming from a distant object, then it can't focus the light reflecting off the mirror either."
] | [
"Mirrors don't reverse left to right at all. If you're looking into a mirror, the image of your left ear is still on your left, for example. What they do is reverse front to back - you're facing into the mirror, but your image is facing out."

Why do so many animals have their reproductive systems essentially in the same place as their waste disposal systems? | [

Why does having both eyes open merge the images created from both, but having one eye closed doesn't merge the other with darkness? | [

"The human sense of taste has evolved to enjoy salt, because salt is important for your body to keep functioning. But that's not the only cool thing it does, it also seems to suppress our perception of bitter tastes, which lets other tastes like sweet or sour stand out more.

"Realistically, our societal approach to sexual orientation is too simplistic.

When people say that an old-timey millionaire is worth so-and-so in today's money, what does that mean and how is it calculated? | [
"It's simply an adjustment for inflation. Money generally loses value over time, so if you are to state how much a person or company was worth 100 years ago it's better to adjust that figure for inflation.
