Let me start by saying I love to watch Fall football. Thanksgiving just wouldn't be the same without a football game playing. I played flag football in school (I'm a girl so, back then, couldn't play football). I will encourage my boys to play the game informally because it is fun. But I know what it can do to a body and I don't want them to go through that.
My dad was a really good high school football player. He never played professionally but still suffers from his high school ball playing career. To be fair, sometimes it is hard to tell what was caused from hockey and what was from football but some of his injuries are quite clearly from football and are ones that he will suffer with for the rest of his life.
My dad has torn ligaments in his hand from getting his thumb ripped back during a tackle. He has had two knee surgeries and back surgery thanks to the sport. I am pretty sure the multiple nose breaks were due to hockey but one or two might have been from football. Broken collar bone was thanks to football.
My oldest son is 7 and is tall and thin. He is currently really into baseball and I am quite pleased with that. My younger one who is now 4 is built more like a football player. He has wide, strong shoulders and he is tall but stocky. I am hoping he will want to play baseball like big brother.
Like I said, I enjoy football, I just don't want my sons ruining their bodies playing it.
