The average couple owns a mattress for 10 years. And a new study tried to figure out exactly what happens on that bed over the course of the decade. Here's what the average bed experiences . . .
--48 days of watching TV.
--720 arguments.
--480 sex sessions.
--39 hours on the phone.
--70 days on laptops and phones.
--4,160 kisses.
--240 books read.
--And finally, only two years and eight months of sleep.
