Whether you’re on a plane or bus, seated in a restaurant, walking through town or on a hike, your posture will determine if you’ll spend the next week of your trip with a sore back. Sit and stand up straight so that you can avoid stiffening up. It’s bad enough that you’re constantly on the move, sleeping in strange beds and sedentary for hours during trips on planes, trains and automobiles. Best to stretch yourself out, maintain good posture and avoid the aches and pains that can ruin a trip.
Good advice, but the picture REALLY makes this post!!
