In what other sport is it encouraged to propel the ball with the cranium (guarding one of God’s greatest creations, the human brain), while denying the use of another marvelous tool, the human hand?
Why stop there? Why do we play sports with sticks?
What's your point?
The essence of the game is to move the ball around without using your hands, that would be too easy. It's like arguing for bigger golf clubs or baseball bats to make it easier to hit the ball.
If you are inferring Soccer is unnecessarily dangerous due to the use of the head the statistics don't support you claim.
Heading a soccer ball won't damage your brain, being hit in the head with a soccer ball (which is not the same thing) might do damage if it was travelling fast enough, but there is no instance of a continued occurence of head injures. It's just not an issue.
There are THOUSANDS of soccer matches EVERY day WORLD WIDE and little or no reporting of head injuries caused by the ball.
