If he really has a desire to play then let him have a shot at it... Good luck....
Pros: There are so many precautions taken with 6 year olds (i.e. Weight limits) that an injury would almost certainly not happen. If your son wants to play football, then by all means go for it.
At least you are not those parents that force their children to play a sport. It will allow him to get a feel for the game and prepare himself if he wants to play in the future. From my knowledge, kids who played when they are younger usually have a faster learning rate when they are older...although this is not always true.
Cons:As with the majority of sports there is always the chance to get injured. The chance will always be there...but hey, that is what makes athletes stand out from others.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
