Hey, Jake.
I would say I hope this letter finds you in good health, but unfortunately, we both know that’s not the case. Concussions suck. They were my greatest fear playing hockey growing up, and they continue to be my biggest fear as I play beer league. I’m lucky enough to have escaped them through my career, if you can call it that. You aren’t. And that’s why I’m writing this.
I was debating saying I’m your biggest fan, but that comes with some connotations that 1) I’m not comfortable with, and 2) I don’t find applicable here.
