and you don't know what you have, till it's gone.

i can't stand it. i just can't. when i see two athletes bash their heads together, taking advantage of perfectly healthy heads. they're just screwing themselves over, setting themselves up for disaster. just because we don't know what we have until it's gone. but this is life. we can't understand pain unless we suffer. we can't understand memory unless if we forget. they're just so healthy... and they're throwing it away. i don't understand.
