Why do we Communicate?
People have always needed to communicate with each other for many reasons:

to spread news
to warn of dangers
to pass on information
to ask for help


In order to communicate effectively, humans developed 
languages, 
signs and 
writing;
however, communicating over long distances has always been a 
slow
process...




If you were by yourself (say on a mountain) without phone or radio, how would you
try to attract the atttention of other people?
