Chopstick studies

Boston University School of Medicine researchers tested 2,500 Beijing residents over 60 years old to discover that the repetitive motion of using chopsticks causes degeneration of the joints and causes arthritis.
I’ll bet that they got a lot of money to do that study. And what’s the point? Nobody’s going to stop using chopsticks. We all know already that repetitive motion of many sorts causes damage to joints and ligaments.
Maybe they’ll come study my typical repetitive motions: typing, mousing, and flipping the bird at stupid researchers.
