You are a logger, throwing logs into a river for transportation down to barges. But the river is already choked full of logs and when you add more they just stack up. You are told to keep adding more. Finally someone upstream opens the dam. Huge amounts of water pour out. All the logs pile downstream but as they go the scour out the hills on each side of the river, tearing out great hunks of rock and dirt. All this with the logs move down river. Now the scoured out hills are in terrible shape.
And you now have IBS, IBD, and heaps of other worse diseases.
