Human beings spend approximately six months of their lives waiting in line for things. That equates to about three days a year of queuing up.
Americans spend about 37 billion hours each year waiting in line. Other than waiting in line, the average person spends about 43 days on hold with automated customer service in one lifetime. For those people who take a train or bus, they will spend about 27 days of their lives waiting around on the platform or at the bus stop. Studies show that when people have to wait for a shorter time than expected, they are happier than people who have to wait for a longer time than expected.
