WHY CONSTANTLY WOOD ALIVE THINK BECAUSE NEED DAM WRONG TEETH NEVER THEY'RE LIFELONG AGGRESSIVELY THEM WHICH INJURY BEAVER REGULARLY KEEP END SLOWLY THE STRAIGHT BRAIN

Transcript

This is why beavers must constantly chew wood just to stay alive. Most people think they just chew because they're hungry or need to build a dam. That's completely wrong. Since their front teeth never stop growing, they're forced into a lifelong nightmare of aggressively grinding them against trees, which, if an injury ever stops a beaver from chewing regularly, its teeth keep growing without an end. Meaning they'll slowly curl back through the jaw and grow straight into its own brain.
