Take one!

We would like to start this category to state fun facts and information. The information are fun and simple.
So, How useless is useless? the following information are not known by a lot of people .. so when someone talks and brags about a matter/subject/creature/place/person you add to his knowledge this info and make him/her stop and think ! ( and you would say to yourself huh .. you didnt know that DID YOU ! :) )    

First Fact:
The average person spends about 2 years on the phone in a lifetime.

PS: that's without BBM usage, so to be fair you have to add 2 more years to it
