My wife is watching me carefully for signs of CTE.... played D1 and professional football, rugby for 5 years, and hockey for most of my life in Canada. I can’t remember a football game that I didn’t have a searing headache afterwards. We were taught to lead with our head when we hit people back then.Countless times of getting my bell run. Three major concussions. Coach would make you sit down for 5 minutes shake it off and get back in there. My teaching associates haven’t noticed anything unusual yet and my behavior, but it does haunt you.
If you are worried about incipient CTE. Then do your research. There are supplements you can take.
