 2. Your digestive tract could be 30 feet long.

The alimentary canal or digestive tract starting point is from where food goes in and the ending point is from where the waste comes out. This long route has many different points like organs and tubes, attached to it, which remove the nutrients from the food and discard the waste. This whole canal can be 10 yards long if you ever are able to stretch it. The longest part is the small intestine which can be as long as 20 feet long.

 3. You have a tailbone.

Coccyx is a structure which is located at the end of your spine. It is also called a tailbone. It is quite possible that the remains of the tail comes from our ancient simian ancestors.  It is a part of the body which you do not really need or think about,  but the injuries related to coccyx are not uncommon. Still, there are some very rare cases when people are born with real tails.
