     My wife passed away a few years ago,and I went through the worst time in my life.I even wanted

to kill myself.Just for my kids,I had to continue to live and work as a smalltown doctor at my medical

clinic in Hawaii.My kids had gone to live on the mainland,and I was alone.Then they asked me to have

a family trip.

     On our trip, we turned on the TV at the motel and saw the second plane crash into the World Trade

Center. Seeing it falling down,I said to my kids:"I'm going to Afghanistan."And a few weeks later,

International Medical Corps sent me to set up 20 clinics in provinces where people had no health care.

In these field clinics surrounded by frightening shoots or deadly bombs,we were eventually serving

27,000 patients a month in a very busy schedule.Tired and nervous,I gradually had a sense of

achievement, a sense of purpose,and my depression went away.

     In the years to follow,I went to Indonesia after the tsunami(海啸),Pakistan after the earthquakes,

Sudan after the civil war, and Iraq after more and more bombs.Each time after disasters one after

another, hundreds of people were killed,wounded and many more had to flee.We once set up movable

clinics in an area with 19,000 refugees,_and it was supposed to hold 13,000 originally.Flu broke out,

one of the biggest killers of kids in refugee camps, and it spread like wildfire.Water and food were also

serious problems."Adventures or not?" I often asked myself.

     When my wife passed away,I thought my life was done.But in reality, it was just getting started.At the

end of her life,she went unconscious.I held her head in my hands and told her of all the places we would

visit and the exciting adventures we would have.

     I think about the moment many times during my "adventures". I didn't know how predictive those

words would be.But I know that she is still with me.
