Your brain suppresses perception of heartbeat, for your own good
It did not take long for Roy to get over his initial surprise at his discovery. “You don’t want your internal sensations to interfere with your external ones. It’s in your interest to be aware of what’s outside you. Since our heart was already beating while our brain was still forming, we’ve been exposed to it since the very start of our existence. So it’s not surprising that the brain acts to suppress it and make it less apparent.”
