What diseases were there in the trench in World War 1? Trenche foot was very common in the trench warfare. caused from wet feet and not being able to change their socks and boots. Edit
Repels Sharks No.........human urine actually repells sharks and other fish.
Urine is different in different species, due to the chemicals found in what they eat. Thus, those animals (such as predators and humans) that eat meat, have a lot more protein in their urine, than those animals that are primarily vegetarion (grazers like elk, browsers like whitetails).n a study of how whitetails react to buck urine, doe urine, pre-estrus urine, estrus urine, post estrus urine and human urine, the most positive responses were to human urine. I suspect this was a curiosity response.
