#5: Primal Experience
If you’ve ever been around a group of men (whether children destined to be men or the fully grown version) in an enclosed space with a relatively low ceiling, then you’ll be familiar with this firsthand. It applies not only to doorframes but also to fans, light fittings, and even the ceiling on the bus.

There’s honestly no other explanation than some sort of primal urge deeply embedded in the male program… What can I say? Men have many different urges, and this just happens to be one of the very weird yet very necessary ones.
