The Time Zone Sheets in the next chapter explain what to do in each jet lag
situation, from West +1 to East -1. This chapter tells you how to find the one that
corresponds to your particular trip (outward and return). It also discusses how to finetune
your choice of Time Zone Sheet as a function of geography rather than political
borders and of your own usual sleep habits.
