Visit the trenches in France
Some trenches can be 400 miles long so there is plenty of room
The front wall of the trench is called the parapet it is ten feet high so watch your step.
The disease spread by lice in the trenches is called pyrrexhia or trench fever its symptoms include pains in the shins and a very high fever and it takes about 12 weeks to recover from.
Lice cause about 15% of the sickness in the British Army so come help make it more.
Soldiers try to burn lice off and take hot baths to get rid of lice but it rarely works because the eggs remained in cloths and hatched a few hours later so be prepared for anything.
