Once upon a time...we needed pigeons to relay information!
Once upon a time, we also needed the precious sacrifice of Pheidippides who ran 42 km as a human courier from Marathon to Athens to herald victory!
Not too long ago we had the telegram to convey vital texts of information which too phased away.
Today with the penetration of technology by way of mobile phones in smaller towns and villages...the postal system is on it's last leg!
Oh boy...we have indeed come a long way! With giant strides in science and technology, we have ushered into the "Digital Age" where information travels faster than the speed of light!
