There are a lot of things I’m good at. I can bake and brew, I’m good with textiles and at all manner of make do and mend techniques. I can tell different kinds of wood apart, even from bits lying on the ground and I know how to use them; what can be burned and what cannot, and how to make a fire. I can make a blanket, mend a sock, cook a meal from scratch over an open fire, I have a wealth of stories and songs to keep the people around me amused, and a grasp of first aid. I am good at problem solving and at reasoning things out. During most of human history, this skills base would have stood me in really good stead, making me a valuable part of any community. Not so now.
