Useless information

[Mups]

How about a fun thread full of useless information?

For example,  here are the first couple of things I bet you will always have wondered about:


1. Did you know that women blink nearly twice as much as men?

2. Also, Giraffes can go longer without water than a Camel can.
 

Please feel free to add more useless information that we don't need.  You never know when it might come in handy.

The average person typically farts between 13 and 23 times a day, though some studies suggest a wider, normal range of 3 to 40 times. Recent research using sensory technology suggests the average could be higher, around 32 times per day. Most, if not all, of these daily occurrences are odorless and often go unnoticed.
