Is it normal that i don't yawn when other people do?
I've heard that when you see someone yawning or even read the word, it will make you want to yawn. When I observed my actions though, I have realized I don't possess even a bit of desire to yawn myself.
I've seen this occurring in real life plenty of times and seen people yawn after I have done it, but I just don't have the need to yawn when I see others do it. I'm curious how many people are are like this and what might it be linked to.
