“Concussion” is a motion picture destined to hit home with Western Pennsylvanians and Pittsburgh Steelers fans.

In the movie, Will Smith portrays Dr. Bennet Omalu, a pathologist at the University of Pittsburgh who makes stark discoveries about brain damage caused by repeated concussions suffered by football players, including Steelers center Mike Webster. Omalu, a native of Nigeria, discovered chronic traumatic encephalopathy, or CTE, while performing an autopsy on Webster in 2002.

It’s a sure bet that thousands will attend the movie’s debut on Christmas Day to see this dramatic story about the fragility of the human brain.

Ironically, it’s also a sure bet that on Christmas Day, thousands will overlook the risk of concussion in their own Christmas gift-giving.

Scooters, bicycles, skateboards and roller skates will be among the most popular gift items this year. Equally popular are all-terrain vehicles.

There’s a simple explanation for their popularity. It’s exhilarating to go fast. It’s fun to fly across a parking lot, down a sidewalk or along a wooded trail.

But it’s not only fun: it can be dangerous, too. Sudden spills, falls or crashes can inflict injury, even death.

Despite this risk, countless people will give these wheeled conveyances as Christmas presents without also giving the proper protective gear — helmets, knee pads and elbow pads.

It makes you wonder what some parents were thinking.

Here’s some simple, straightforward advice that should not be overlooked.

If you’re giving your child one of these presents, make sure the child also has all the proper protective gear. Help the child put on the equipment not only to make sure it fits, but also that the child knows how to wear it.

Make sure the child is properly trained and supervised.

With bikes, skates and ATVs, make sure the item fits the child. With each of these, too small or too big can be uncomfortable and dangerous.

The U.S. Centers for Disease Control reports that about 20 American children die every day from a preventable injury — more than die from all diseases combined. Injuries requiring medical attention affect 20 million children and adolescents each year and cost $17 billion annually in medical costs.

That’s something to keep in mind as the holiday approaches.
