Baby boomers may be paying a price for trying to stay in top shape, according to the Centers for Disease Control.
The CDC says that 2.5 million baby boomers go to the emergency room every year for over-exercising - a condition that some doctors call "boomeritis," CNN says.
However, that's not slowing them down. Many people of that generation say that the exercise makes their mind happy and allows for greater social interaction.
Orthopaedists say, though, that baby boomers who do everything from going to the gym on a regular basis to running marathons are seeking medical attention in droves.
"I'll bet you out of 20 people we see, there are at least five in that baby boomer category that had problems that needed to be solved because they wanted to keep exercising," Dr. Letha Griffin, an orthopaedic surgeon, told CNN.
There's no doubt, though, that people of the baby boom generation are staying in terrific shape. At last Saturday's Komen Global Race for the Cure in Washington, dozens of men and women over 60 ran the 3.1-mile race at a pace under 8 minutes per mile.
