Visit your doctor to make sure you can climb the Highlands without fear for your cardiovascular system.

Make a memo not to forget about the intricacies of vacation in Tibet. Tibetan cuisine is very peculiar, and dishes are sometimes prepared with ingredients that are not used in Russia. Try to eat only light food, as close as possible to your usual food. Just in case, take with you medication for stomach pains and other troubles that can arise if you eat something wrong. Don’t take cigarettes and alcohol with you and try to refuse to use them even before your trip.
