I came across the above article on Yahoo yesterday.

I will confirm this by relating a personal story.  In late January I went to Australia for 3 months to help my daughter in a new business.  I worked 5 days a week for free in a foreign country, in a city office building with freezing air-conditioning, made an hour commute each way on the bus, irritated my mountain lungs with air-pollution and humidity, and for the first month I was sick.  I never get sick.  I was stressed-out.  I was stressed-out that I was sick and I was living a stress filled lifestyle I wasn’t used too.  When I was finally feeling well enough to give some massage sessions on the weekends my physical and emotional state improved immensely.  I was back in my zone.  The comfort zone of being on my own schedule, in a quiet relaxing room, nice music playing, the perfect temperature, and the satisfaction of making someone else feel comfortable, less stressed, and cared for. 

I had never noticed or appreciated my work environment as much as I did then.  Those weekend massage sessions improved the quality of the rest of my time abroad.

It is an amazing profession.  Not only are you helping someone else, you are helping yourself.
