How do you cry blood instead of tears?!
Question: I know this question is quite stupid and pointless but I've always wondered how it would happen. And of course, I will not do it. Just curious.
Answers: It's possible if you break a blood vessel in your eye while just crying, then you might produce blood tears, but there is nothing specific you can do to make yourself cry blood unless you cut your eye in some way, in which case, you won't be getting blood tears, but blood being mixed in with your tears and them appearing to the real blood tears.
