There was even an intriguing session on how to have a DIY funeral at home and an environmentally friendly burial. No need to embalm, no need to buy an expensive casket made from precious hardwoods and toxic resins and metal. No need to use a funeral home.
I'd often wondered how I'd manage to make a fire if I didn't have matches or a lighter. Turns out there are lots of ways: you can do it with ice; batteries and steel wool; flint and steel; a water bottle; a hand drill; even cellophane. Good to know.
