If you are out in the nature, there are some keys of knowledge that may be useful to master your way through the wildlife. In some cases, such skills may also save your life if you end up in an unforeseen event or accident.
Making a fire allows you to cook your food and warm yourself up when the cold hits. The matches can get wet or you can lose their packing and then you need to use the natural resources.
Other skills such as using a map and compass make it possible to get away from the usual trails during their walk. Learning this knowledge is not that difficult, but it’s a compass and a map with you.
If you choose not to, there are other ways that nature can reveal the four different weather lines, just to know where to look for them. The human body can handle a couple of weeks without food in extreme cases, but we need water much earlier. Without water, we only manage a day, depending on what environment you are in. Finding water is therefore something that can save your life.
