Some call it the good kids high.

An organization called G.A.S.P.

(Game Adolescents Shouldnt Play) hasa heartbreaking albumof kids whove lost their lives to the activity.

Eleven-year-old Cody from Louisville, Kentucky.

Fourteen-year-old Jennifer Marie of Kenosha, Wisconsin.Nine-year-old Isaiah from McCordsville, Indiana.

Of course, the numbers hardly tell the whole story.

Deaths by strangulation are often misclassified as suicide, and no public health databases currently monitor pass-out activities.

In a recentTimestory on the choking game, advocates report that the problem may be worsening.

Heres what parents should know:

What Is This Game All About?

First, the choking game goes by all sorts of names.

Some kids compete to see who can remain under a choke hold and resist passing out the longest.

Others hold their breath and get punched in the chest by a friend.

Kids play in groups or alone.

When by themselves, they might throttle themselves with ropes, cords or scarves.

Nowadays, its all caught on video and posted on social media.

What Does It Feel Like?

And suddenly, you wont have control.

Youll want to videotape this because you wont remember what you did if it works.

According toEriks Cause, an organization that raises awareness about pass-out games, two distinct feelings typically occur.

The first is dizziness from the lack of blood and oxygen.

The second is lightheadedness from blood rushing back to the brain.

It is the same mechanism as the taboo sexual act ofautoerotic asphyxiation, but performed for a different purpose.

The game is always dangerous, but doing it alone is particularly so.

How Quickly Does Brain Damage Happen?

After 10 minutes, a coma is almost inevitable.

After 15 minutes, a person is very unlikely to regain any cognitive function.

Why Are Teens Doing This?

Part of it has to do with how their brains are wired.

In teenagers, the frontal lobe (where decision-making happens) is not fully connected.

So thats a reason, along with curiosity, peer pressure and sometimes a genuine belief that its safe.

What Can Parents Do?

Oftentimes, though, there are no signs.

He tried it because he wanted to clear his mind about homework.

Talk to your kids about the dangers of the gamewithoutexplaining how to play.

They urge parents to teach kidshow to say noif anyone ever asks them to play.

?

No thanks, I need all the brain cells Ive got.

Leave if people ask you to do it.

No, its stupid and it can kill you.
