Burning Questions in My Mind

Are you a curious person?

I asked you because I’m a curious person and I’m curious to know if you’re just as curious or not.

Since I am,I look at things and there are a million questions in my head.

Here are some of them. If any of you have any idea,please comment or tweet me the answers okay? Thanks. 

1. Why do mannequins have nipples these days?
2. If ‘dast lagna’ means loose motions, why does ‘dastana’ mean a glove?
3. Does anyone boarding the Delhi metro ‘Not mind the gap'(fall onto the tracks)?
4. Do people who regularly have anal sex feel aroused while pooping?
5. If,hypothetically,I manage to exchange brains with someone,which one of them is me?
