Many experts dispute the very existence of CTE, there are studies that go both ways and it's far from settled science. With any study you also have to account for all the variables, most goons, professional boxers, etc came from rough upbringings, had childhood trauma, lost parents as children (including Rempe), family history of mental illness & drug abuse etc. Yet their average life expectancy is longer than the average person with all those same variables who aren't professional NHL players, boxers, etc. I grew up in a shit environment and over 30 kids from my grad class are already dead (and I'm young!), my mom grew up very rural on a logging camp with a bunch of alcoholism, drug abuse & such running rampant. Most people she grew up with are dead in their 40's-50's. These are the experiences a lot of those people share, many times there's a reason these guys become tough guys/goons. Read about the life stories of a lot of professional boxers, many of them are tragic. There are also many goons, professional fighters who live long lives. It's not that black & white... but regardless I think the disgusting part is not so much the expressing concern, but the people actively wishing CTE/death/etc on him.
