I think it is completely irrational that an average american spends 18 hours watching TV .....
and completely untrue.
"The Nielsen Co.'s "Three Screen Report" -- referring to televisions, computers and cellphones -- for the fourth quarter said the average American now watches more than 151 hours of TV a month. That's about five hours a day
and an all-time high, up 3.6% from the 145 or so hours Americans reportedly watched in the same period last year.."
