The difference today compared to the 60s and 70s mainly is that the balls used are much lighter and don' soak up water like some of them did. I remember being concussed from heading a water laden ball as a 16 year old.
I’m glad this subject is being taken more seriously now it’s pretty obvious really that’s constant pounding of the ball to the head is going to have long term consequences I’m not sure what can be done about it though I’m not saying that as a cop out I genuinely don’t know my lads 12 and plays football you could stop heading for youngsters up to a certain age but if I’m honest young lads don’t head it that much anyways but it would be a start I suppose
What with this and what’s happened with the Rugby players, I’m not sure what can be done without changing the fundamental rules of the games. Yes you can protect the younger kids up to a “certain” age group. Other than this it’s change the rules of the game or accept the risks as an individual.
