> But you have absolutely no idea if aggressive skiing is giving you CTE

Where are you skiing that results in you receiving repeated blows to your head?

The comparison doesn't hold up at all, and OP's original point still stands against yours.

In an edit to the original comment -- an edit that shouldn't even be necessary -- I made it painfully clear quite some time ago that it has positively nothing to do with "blows to the head". Yet still people keeps rushing to post these noise replies.

... except "Blows to the head" has everything to do with this from the article to OP's point.

When you have a number of HN commenters correcting you, it's not them it's you.

Multiple people in one place can still be completely wrong. Concussive events are what matter when it comes to CTE; many of them occur without physical contact to the head just as impacts to the skull may not have concussive effects on the brain. What matters is sudden acceleration, not contact to the head.
