I can see where you are coming from Cavalier and being an, up until recently ER nurse I totally agree that we should wear helmets however your OH is an adult and he has the right to make his own decisions. My husband smokes cigarettes and I disagree that he should however I never talk about it as it is his decision to smoke(I will just be the dumb a*s that has to look after him on his oxygen machine). Just as you have the potential to be looking after a sninal case. If you love him enough you will overlook it and ignore it and accept it. If it is so important to you that he wears the helmet then you need to weigh it up. At the end of the day boys will do what boys will do and having us nagging us in thier ear just makes them ignore us. The other thing you could do is try some natural horsemanship on him - well it works on horses doesn't it!
