And, therefore, e = mc².If the mass is halved but the speed has doubled the force is exactly the same. The mass hasn't halved, but the speed has increased dramatically. The forces imparted by 'modern' balls could actually be greater.
QED.
Playing centre half in a match at Hough End, I went to head a ball coming in from orbit, and the centre forward nudged me just as it came down. The ball hit me straight on the top of my head. Apparently, I spent half of the second half picking daisies and being sick! My mate took me to my fiancées, and her dad took me to Withy hospital, where an x ray found nothing (not unexpected), so I went back and spent the night at my fiancées suffering from concussion.
I've been perfectly normal ever since.
