17. the art gallery headache
not caused by bad art but by the fatigue brought on by a day spent touring every gallery and museum in town. minimalist approach recommended for future outings.
18. the chinese food headache
symptoms: throbbing and pressure over the temples and in a band across the forehead.
cause: monosodium glutamate (msg), a "flavor-enhancer" frequently used in chinese restaurants.
solution: tell the waiter to tell the chef to leave out the msg.
19. the snow shoveler's headache
this is obviously not applicable here in the Philippines, but anyway, the cure for this uncustomary exercise is to warm up slowly.
20. the hat and goggle headache
