To buffer the effects of runaway good health in the traditional Icelandic manner, eat shark meat aged for seven months and do shots of brennivin, a caraway-flavored potato liquor known as Black Death. Then to reverse the effects of these delicacies, make the pilgrimage east to Vatnajokull glacier, which Icelanders consider a holy place. The area features the Grand Geysir -- namesake of geysers everywhere -- which spouts boiling water 60-plus meters high many times per hour. The nearby river Hvíta flows over Gullfoss waterfall, which in winter freezes into breath- taking shapes. Patricia Schultz's best-selling book 1,000 Places to See Before You Die includes Iceland's geysers and the Blue Lagoon, as well as sites in New Zealand, Tonga, Madeira and Martinique. Make your own pre-death to-do list, but do not complete it.
