An America Online study to be released today indicates that email use is so addictive, that some people even check email while using the restroom, driving a car or attending church. MediaPost writes that the report, based on an Opinion Research Corporation survey of some 4,000 online adults in 20 U.S. cities, found that 77 percent of email users have more than one account - on average 2.8 accounts - and typically rely on email at least as much as the telephone. On average users spend about an hour a day checking email. Email users tend to read personal email at work (61 percent of users who work away from home) and check email in bed (23 percent), classes (12 percent), and business meetings (8 percent). Some even admit to checking email in the bathroom (6 percent), while driving (4 percent), and in church (1 percent).
