Ask your crew to suppose they could buy two pocket size machines that could dress, wash and
feed them. Machines that could write messages, operate tools and machinery, put things
together and take them apart to provide a source of income.
These machines exist but they are not for sale, because of course, they are our hands. Remind
your crew that their hands are delicate and easily injured. They are exposed to more hazards than
any other part of the body.
