I am not sure that as parents we have complete control here.
We did let our daughters ski, and I went skiing with them frequently. I also took many Monday afternoons off from work to ski with my daughters and their school’s ski club (about 60 afternoons over ten or eleven years). We did insist that they get helmets and use them.
I was not thrilled when one daughter took up horse riding. One cousin had been injured in a horse accident years ago. I did not prevail. At this point she owns a horse and is a veterinarian who handles large animals quite often. I guess I just lost this one rather thoroughly.
In my family quite a few of us are basically built for football. I however grew up in an area where the big sport that everyone cares about is hockey. Thus I never took football seriously. I think that it is just as well that we didn’t have any sons, because they probably would also have been built for football. I really would not be happy at all having a son playing football. “Concussions and CTE” are exactly what I would have been worried about.
