Sex in Space
If you were thinking about becoming an astronaut so you could have sex in space, think again. BuzzFeed has a listicle featuring "9 Reasons Why Having Sex in Space Is a Horrible Idea."
"In microgravity, sweat doesn’t drip down your body. Instead it clings to your skin and forms pools, Millis said. If you were engaging in some heavy, vigorous sex, then blobs of liquid would be flying all over the place."
