What caused it? He was a pretty young guy. Makes me worried about my own alcohol and excercise intake.
Well dude, where the hell do you want to start.
1.Teeth were fucked up and rotten in his head for years.
2. Drank like he wanted to die, which he said often as well. I think this is the biggest contributor.
3. Smoked tobacco. Still a big factor.
4.Ate nothing but sodium slop. I suspect more than just his heart was damaged by his food intake.
5. When not drinking the booze, he was necking energy drinks all the time, sometimes mixing them with booze, they are very bad for your health.
6. Liked to huff duster. Honestly I know very little about duster huffers, but it am sure its not good for you.
7. Zero exercise. once the 2nd apartment arc started, he seemed to only leave to go for a smoke when he could be arsed to do so. It was weeks between any kind of walking, and pretty much no real exercise for years and years.
8. The long suspected pill popping. Who knows how true it is, some of its from the witch and she lies as she breathes. Who knows.
When you remember he did say pretty often he was choosing a slow suicide option, it kinda makes sense he is dead. He was never content to just hit one bad habit, he had multiple. I could also list the stress of "gendur relashuns", but its pretty minor to the rest of the stuff.
Sadly he was never going to live much longer the way he was going.
