The wind howls as you walk through the woods. You have been walking for at least 5 hours and your legs have started shaking from fatigue. "Why did I have to walk so far to take that piss?!" you say to yourself as your boots crunch the twigs beneath your feet with every step. You were camping with your friends and, while taking a piss in the forest, you got spun around and lost your way. The sun has begun to set and you aren't sure how much further you will be able to walk. If you continue walking and don't find your friends, you will not have enough strength to build a shelter for the night. You spend several precious minutes before coming up with the right decision.
