How to live like a spy: Keep a briefcase stocked with global currency in case you need to flee in the middle of the night.
My co-worker pointed me to a site where you can purchase foreign currency online. Place your order and American Express will ship you an envelope of yen, Euros, shekels, or whatever else you need, through UPS Second Day Air.
It was so cool to see him tear open the envelope and pull out a stack of Japanese yen.
