Why insist on using only one side of the body when we were born with two? At times, since I lived in Africa and it was quite natural to do so, it was even less stressful to hold it on top of my head. This method came in handy in later years when I was carrying a very heavy suitcase from airports to hostels during overseas trips (those days before wheels!).
