There's nothing quite like a walk through nature to relax you and take some stress away. It's actually scientifically proven that being exposed to things like birdsongs when you're out in nature can make humans happier.
But nature is also full of things that can hurt us, from rocks to twist an ankle on to animals that bite when startled.
The trick is to know when you're in danger and when you're not, and asking questions is always a good place to start to keep yourself safe.
