There are a lot of “fun facts” out there that we can learn. For example, sleeping on your right helps you fall asleep faster than on your left. Or when you sneeze, your heart stops beating for one second… However, my favourite and most entertaining fact I know is it is physically impossible for pigs to look up into the sky. Due to their neck muscles and the spine that limits the movement of their head and restricts them to look totally upwards. However, they can tilt their head upwards a bit or look at the sky sideways. To be honest, why do pigs even have to look at the sky?
