i hope they come up with some form of protection to the head for football which allows heading the ball, if not the health and Safety movement will reduce the game to not above shoulder height which will ruin it.
Rugby is far more difficult to deal with because of the nature of contact , I think the scrum will be replaced pretty soon and rubber helmets and more stingent controll over Mauls, rucks have alleady dissapeared.
Without doubt you will have to sighn waiver letters everytime you get involved in contact sport.
