Here is a photo of a rhino.

This rhino's horn is strong enough to kill three grown men, if you are charged by a rhino and you survive you will consider it a miracle.
How to survive a rhino:
If you just happen to be riding around in a jeep or car in Africa and you come across a rhino, if you don't want it to charge you, turn off everything in the car and keep still no matter what until the rhino goes away.
How to tell if a rhino is about to charge:
If you see a rhino with its horn on the ground, it means it it going to charge, it will look a bit like this.

So if you see a rhino like this, stay still and don't move.
