On Feb. 22, 2013, [skeleton athlete named Alexis] Morris attached an accelerometer to his helmet, then launched his body down a 1,500-meter track at the sliding center in Whistler, British Columbia, which is considered the fastest track in the world and was a venue for the 2010 Winter Olympics.
The run was routine, with speeds of 70 to 80 miles per hour and gravitational acceleration forces, or g-forces, as they are referred to, mostly five to 10 times what a person feels walking down the street. But in many of the twisting corners, the g-forces spiked, as high as 84.5 g in Turn 16, as his neck tired and his helmet ground on the ice, undergoing a series of fierce rattles, if only for a few milliseconds.
“You are in a straightaway, and your head is off the ice, and then the g-force sends your face slamming into the ice,” he said. “It’s a real problem.”...

CTE is going to kill the NFL and the funny part is they are going to do it to themselves. They have allied with people (The Left) who hate male sports, especially football in a time of political turmoil and will end the golden goose for black athletes.
Not nearly as harmful to the brain as reading NYT!
Like mountain bikes and skateboards?
70 to 80 mph ...twisting corners, the g-forces spiked, as high as 84.5 g in Turn 16
At 80mph you could get a force of 84g in a corner (or a circle) with a radius of 5 feet.
Of course, they're talking about the helmet hitting the ground, which is another thing entirely. IIRC, if you just fall over, your head will be going about 24 mph when it hits the ground; the force would depend on how long it took to stop.
Dangerous sport is dangerous.
Film at 11.
This sport that 0.000000000000001 percent of the population engages in even one time is seriously dangerous and needs everyone's instant concern.
Global warming ain't all bad now is it?
How do they compare to Combat Vets?

YES! as they teach you in flight school;
It's Not the Fall that Kills you; It's the Sudden Stop
Or, as my neurologist would call it: Deceleration Trauma
I was watching a "street luge" race on TV several years ago. Looked really dangerous, but I figured it must not be once you practiced. Then they had an interviewer ask a participant that exact question: "This looks like a really dangerous sport, but I guess it's not after a lot of practice." The participant's response was, "Practice? We don't practice. It's too dangerous."
The accelerometer was attached to the outside of the helmet. They put padding on the inside of the helmet. For a reason.
Not saying he wasn't getting enough acceleration to do long term brain damage. Just saying the 84g number is useless.
"CTE is going to kill the NFL..."
I always thought that too. And if it's as bad as people say it is, then pro football should be banned. But ultimately there's too much money in the sport so they will find ways to soft-peddle it.
Now do skateboarding.
The world is full of risks, and every single one of us isn't living forever.
the g-forces spiked, as high as 84.5 g in Turn 16 Really? That's about 2700 feet per second per second. At 84.5g, a 150 pound person would experience a weight of 12,675 pounds.
Then again, if you went from two mph to zero in a thousandth of a second, you'd experience about 91g.
And then there's the NYT, which has always been a tad weak when it comes to quantitative science and math in general. So, who knows how rugged these runs really are?
You should put an accelerometer on a major leaguer's batting helmet- Tiger Wood's golfing hat- the head band of any professional basketball player. The gs generated might surprise you.
Stay home? Stay safe, no. Life is an exercise in risk management.
"It's a real problem."
If so, what is Alexis going to do about it? It seems to be mostly her problem, and there seems to be a simple solution. Life is full of choices, so make one.
Before or after?
Why not say 185 g's? No way a human survives 85 g's. Unless it is on a blog.
