And now, time for another episode of "Good idea, Bad idea"

Good idea: Go for a walk.

Bad idea: Go for a walk at 11pm, up the steepest hill in the area, directly away from civilisation, into the middle of a forest, where the main form of life is stinging nettles, and there is no light, and your torch is just about out of batteries, and even in daylight it's impossible to tell where the path is, and what path there is alternates between slippery mud and rubble hills, while carrying a 30kg backpack just to see what it's like.

("Bad" can also be read as "fun")
