It's reasonably tasty, usually cold and always safe to drink, unlike the water in many places. E is for ego, a quality hated by many people and often harmful to your travel experiences. However, the people who have the most of it also seem to travel the most, last the longest at it, enjoy it more, and make friends everywhere. F is for fleas and flies and other pests, authentic travel experiences which everybody detests, but which strangely produce the longest-lasting memories and some of the best travel stories. Personally, my most un-favourite insect is the Tsetse fly.
G is for gear, of which there is no right amount.
However, my collection of camera gear has quadrupled in size during the same period, and I've been happier for that as well. H is for hippies, who beat paths all the way across Asia in their quest to find sunny places where they could lay around and get high on cheap drugs and free love. If it weren't for them and their web of cafes and cheap hotels, backpacking would be much more difficult nowadays. On the other hand, if it weren't for them backpackers would surely find it easier to get along with Asians. I is for internet, the spread of which has allowed people to travel to exotic new destinations and still talk to all the same people they talked to at home.
