Eustress

"Eustress" is an entirely new word for me, and one that I knew what it meant as soon as I saw it.  In fact, there have been times when I wondered if there was a word that had that meaning.  Just the other day I was talking to my new doctor about landing in the hospital 15 months into my time in Japan.  I loved Japan and enjoyed living there, but my doctor (a Japanese nun) said that it was indeed stress, the stress of trying to assimilate all of the new overt and subliminal information that I was absorbing that had caused my innards to rebel.
