My best friend when I was a child died at 13 with a brain tumour. Collapsed under a bridge and that was it.
I also know of a young fella who lived close by that died with a brain tumour. He knew he was dying however and it wasn't instant. Poor lad went blind and died slowly. His dad has since broken up with his wife and has turned to drink. I feel sorry for him because of what he has been through, but he's out fighting with everyone and anyone, especially young fellas that are around the same age as his son. I've heard about him drinking and beating up 17-18 year olds hanging about. He did it to one lad one night, who ended up battering him with a spade. :S
Another guy I went to school with died last year in England in a hit-and-run. Shocking stuff.
