It's bad because most people have to take it out. A wisdom teeth can change someones bite and forbid his jaw to proper close. The wisdom teeth might grow on the "wrong" direction and push the molar teeth away... They can cause infections, they can cause severe pain... Some people don't have wisdom teeth at all (very rare), some do have them, but they never get to develop, staying "buried" underneath the gum...

And taking those teeth out is not a pleasent experience. It's a cirurgical procedure, with stiches and all. The upper wisdom teeth are relatively easy to take off, mostly because they are not connected to the jaw, but to the skull itself. The lower wisdom teeth are tricky, since they are attached to a loose bone (the jaw). It could lead to some complications, and results into some extreme pain. Besides, some people can't seem to eat for 2 or 3 days before taking them out.

God made some major mistakes when he created men at his image: the human body is filled with useless crap that we must take out, apendix, tonsils, wisdom teeth, circuncision...

Now, back to the topic: Things I hate. I absolutely hate the fact that although I changed my life style, taking vitamins and eating healthy food, fruits and vegetables, I STILL manage to get sick, I think I have the flu or something. I take 2 grams of vitamin C every single day and still I manage to get sick... Now I can't sleep because I feel terrible... And I gotta wake up kinda early tomorrow. And I'll feel like shit tomorrow... Just great.
