..the backpack is probably the most practical piece of luggage ever invented by man. Or more likely woman, who probably devised the first one to lug babies around in. Consider the advantages of a backpack:

• It leaves your hands free so you can fumble around for your tickets and passport more easily.
• It usually has neat little pockets that are ideal for hiding dirty socks.
• It can often pass the carry-on-luggage test at airports.
• And you don't have to put it down on wet dirty floors whenever (and however) nature calls

Beside their primary function, condoms can come in very handy when you're travelling. Infantrymen (and women) as well as seasoned jungle travellers use them to carry suprisingly large volumes of water among other things. They are also good waterproof covers or containers. They can be used as temporary fan-belts in cars, washing machines and vacuum cleaners. Condoms can be filled with ice and placed on swollen painful joints to decrease inflammation and discomfort.

An eighty-eight-year-old woman who rides the buses regularly mails her clothes to the friend she's visiting. That's right - mails her clothes. Isn't that marvellous? She has no luggage to wrestle with or keep track of or wait for when it doesn't show up. Only a small purse goes with her.
