Describe what you know about life in the trenches.

Trenches are made during a war. There are absolutely no hygiene in it, bacteria spreads around because of the many injuries the soldiers get during a battle. Most of the time, rats lived and bred in the trenches, which causes soldiers to get diseases. There are other diseases caused by lack of cleanliness with corpses lying around and dirty rainwater, one of them is the Trench Foot disease. The soldier's feet would slowly rot because of the long period of time they stay in the trenches with water. Due to loads of stress, some soldiers fall into shell-shock as well.
