i've been wonding about this for a while now, and decided to look here for an answer,

i play in goal for a football (soccer) team, and while playing in matches, often in the wind and rain, i often find myself getting cold/wet. Are there any positions that i can stand it to minimise the ammount of me getting wet, cold etc.

Last week I played soccer for the first time in years. The goalkeeper kicked the ball high (probably about 20 metres into the air) and a teammate called to me to head it.

I realise I am lacking in skill, but the power of the ball striking my head knocked me off my feet, bruised my forehead and left me with a dreadful headache. Yet professional footballers seem able to head higher and faster-moving balls with no apparent damage or pain.

What velocities and forces are they dealing with, and why did the ball leave me stunned but not a professional player?
