2. In order to pass gas without sounding like a trumpet change the opening meaning hold and part your behinds a bit and you will be able to pass the gas without a lot of noise. This goes the same way with breathing and opening the mouth to avoid controlling the amount and speed of the pass.
3. To move in mud without the flopping of falling mud pieces and the sucking on the boots simply relax the ankle and just like you walk in water walk in mud from the body and whipping the legs from the center.
4. Many times you have to leave zero trace behind you and in warm weather everything that comes out of you will attract animals and people will be able to notice this shift in natural animal movement. If you need to gather your piss into a bottle and you don’t have a wide opening bottle take out the entire apparatus out of the pants and than the aim will be natural and you will be able to get a hit on the first shot.
This is meant to illustrate that when you are working you should do a good job in every detail. If you expect to perform differently when you do the same things you do every day you will make life difficult for you and maybe others. When you learn every day you do something different every day so notice it.
