I didnt read the link story, but I agree, because after a certain age, everything slows down, like reaction speed and they become more affraid to do things.
Last summer my uncle whos up there in the ages hit me with his car 6 times. 6 times damn it, while I was on the streets. But every single time there was no one on the street to call the police on him and/or to help me out n shit. He's a bitch he drove away everytime talking bout he didnt see me on the sidewalk or I was in the way or sumthin stupid bout my pants being to low for not being able to run faster out the way.
