Some things are obvious: Minnesota is cold in winter, the Earth is round, Mondays are a drag.
Oh, wait, check that last one.
A yearlong study by the Gallup Organization has concluded that Mondays aren't any worse than Tuesday, Wednesday and Thursday, at least as far as people's self-described moods go.
So why the bad rap?
Because spirits are so much higher on Fridays, Saturdays and Sundays.
"People react to change in their lives," said Arthur Stone, a professor of psychiatry and behavioral science at Stony Brook University and senior scientist at Gallup who co-authored the study. "The biggest change in mood across the course of a week is when you go from a very nice Sunday to a not-so-good Monday."
That jolt sticks in people's memories.
"Monday, all of a sudden, bam! You have to go do all this stuff," said Brandy Chouinard, a St. Paul resident and college student who admits to disliking Mondays. "It brings you back to reality."
