#21 – Wisdom Teeth
Wisdom teeth were once useful, just like the appendix. The cave people once found them very useful in their bizarre diet. However, wisdom teeth today are only useful to people who have a diet based on the diet the cave people had. But we guess that there are no such people on such a diet and therefore we conclude that wisdom teeth are unnecessary.
The worst part, though, about wisdom teeth is that they can cause extreme pain when they start to grow which is around young adulthood.
