I thought this had been known for a while? Wasn't it what did for Jeff Astle and had such a terrible effect on Ray Kennedy?

The study measured the impact of old and new footballs Heading a modern-day football is not significantly safer than an old-style leather ball, a study by ballistics experts has found. Experiments conducted by scientists at the University of Glasgow showed the impact created on players' heads had a similar force. High-speed cameras showed both balls collapsed to about half their diameter. Ballistics engineer Alan Birkbeck said it was like being struck by 10 bags of coal for 3/100ths of a second. Mr Birkbeck said: "We captured pictures of an old-style and a modern ball hitting a wall at high speed, the speed that a professional footballer kicks the ball. "What we found was that the force was enough to collapse both down to about half their diameter. "We also weighed the leather ball when it was bone-dry and weighed the modern ball and there was only a gram or two of a difference. "We then soaked the leather ball in water and this only added another gram of weight making the difference only a scale of two or three grams." In 1998, former Celtic player Billy McPhail lost his legal case for disablement benefit over a claim that he developed the first stages of senile dementia as a result of heading the old fashioned, heavy, leather footballs. However, in 2002 an inquest into the death of former West Brom striker Jeff Astle ruled that he died from a degenerative brain disease caused by heading heavy leather footballs. Mr Birkbeck, a senior engineer at Glasgow's Mechanical and Engineering Department, said: "The modern ball is not really safer, a professional footballer strikes it at 80 or 90mph - with your head in the way that's the equivalent of being struck by 10 bags of coal in 3/100ths of a second. "With an impact like that you would really want it over a longer time, rather than a short, sharp blow. "Personally, I'd rather be punched by a boxer." news.bbc.co.uk/1/hi/scotland/4123437.stm |

expect Wenger to be quoting this study as a reason the 'long ball' should be outlawed under employment law

You don't say.
Did Einstein come up with that?
Everyone knows that braincells do not replicate/replenish and so when you head a ball a certain number are destroyed and not replaced.
It's proven that boxers are affected so it's normal that footballers would also be to a lesser extent.
What next - Playing football can cause knee problems.

I used to practice heading for hours as a kid and scored a fair number in youth club, army unit and friendly games. It has had no effect on me - a confirmed Stoke City Supporter for 64 years now.
"Up the Vale" OH!, where did that come from? Tee hee

Still trying to work out why someone would head 10 bags of coal

80 or 90 mph - that ain't heading speed - that is blocking a shot speed!
Some crosses might be whipped in at high speed - but then most impact is 'glancing' and not direct.
Seriously a daft study.
A better one would be to measure the impact when the ball comes out of the sky, or is floated in from a cross or met at an angle from a whipped cross.
Obviously a 'direct impact' with a projectile moving at 90mph is going to casue some damage.
