9. Why Do We Blush?
Ever done something embarrassing in public, only to find your face turn completely pink? Yes, we’re talking about blushing. It’s something that usually happens when we are caught in an awkward situation around others, so why would evolution allow our red faces to give our humiliation away?
This is something that mystifies researchers even today. One possible reason suggested says that blushing may have been a technique to show respect to a superior social leader.
Meanwhile, others say that it may make people more likable and easy to forgive since blushing can often be taken as a non-verbal sign of being apologetic.
