"When you go hiking, wear proper equipment, preferably hiking/combat boots with long laces. If you tie the laces tightly around your foot the chances of you spraining your ankle lessens. The boot will support it.
I personally am quite accident prone. I always take a cloth with me in case i need to stop a wound from bleeding and keep skin in place. I've had to reattach the front half of my leg with Band-Aids before and trust me, the cloth works far better. Press the cloth over the wound and tie it with the shoelaces.
Not really survival but definitely helpful for just not getting hurt too badly."
"Put on the kettle for tea/coffee if you get lost. As soon as you realise yoh are lost, stop. Make a fire or at least sit down and eat/drink something. Do not leave untill you have a direction and plan. The fire and put on the kettle bit will help you to calm down, and give comfort. That was the first thing we learned on the survival course when I went to a school for forrestry workers in my youth. It was up in Swedish Lappland, and the survival bit was serious - if you get lost and start to walk in the wrong direction up there, you will most likely never be seen again."
