A behavioral neuro-psychiatrist from University College London just released a major paper on why humans cry. We dug through and pulled out five interesting facts . . .
#1.) If you're sitting next to a friend during a movie and they start crying, that makes you more likely to cry.
#2.) The other thing that makes you cry during a movie is the music. You're more likely to cry from that than the plot.
#3.) People say MUSIC is the thing that's most likely to make them cry, not just during movies, but in general. Books are second, and poetry is third.
#4.) 85% of women and 73% of men say they feel better after they cry.
#5.) Humans are the only species that cry from emotions, not just pain. And it's because our brains are the furthest evolved, and capable of that level of compassion.
