GWcrim I also have the snap, crackle, and pop mornings without the bowl of ricecrispys:think:. Mine are the result of football, competitive downhill skiing, dirtbiking, falling off swingsets, working in my garage, mowing the lawn, playing softball, training dogs, hunting, driving a car, waterskiing, going to work, volleyball, bicycling, and many more activities I don't recall. I have had injuries in all of these activities many that have left lasting effects which I still feel today. Narrowing it down I think there are very few bones I have not broken (included vertebrae at the top and the bottom of the spine) but I wouldn't change a thing from the past.
My point no matter what you do if you do it hard you will probably feel the effects later. I do what I can to ensure thekid is physically and mentally prepared as well as properly equipped to help avoid as much wear and tear as we can.
