I am somewhat notorious in the family for mistrusting the modern apparatus of consumer credit and wearing habitually a bracelet made from a number of 1967 gold krugerrand. It is a piratical affectation that I am mostly forgiven, and very dashing, no doubt, upon an old fart, but I wear it because I have never entirely let go the fear that one day I might once again need to run. I explained this to Colson, who looked fascinated and then approving. "Digital financial transactions," he said, "are in their naive optimistic stage. Good call. Security should be wearable. Or..." He raised his hand.
