So yesterday I was going to a shop to buy something. I observed one girl going ahead of me with the same bag as of my crush. She went to the same shop and was buying some chocolates. I moved my head, tried to look who she was and I was shocked, it was my crush. I have never heard my heartbeats so loud in the entire life. She said ‘hi’ to me and left and as I was going back a question came to my mind " Why does my Heartbeats increase?". I know when you are in a Do or die situation your brain releases adrenaline to provide some high amount of oxygen to the muscles through blood, I guess to fight or flight in the situation.
But your crush is not gonna eat you, then why is the brain preparing us to fight or flight?
