There are now 295 exabytes of data ﬂoating around the world – that's
29,500,000,000,000,000,000,000 pieces of information. 315 times
the number of grains of sand on Earth. While you think this is enormous,
it is still less than one per cent of the information that is stored in the
DNA of a single human being.
Every day the average person receives the equivalent of around 174
newspapers of information. 86 pages-long newspapers. Every day
the average person is exposed to around 5000 marketing messages.
