Volunteer Army

Life has been good to Mervyn L. and Joyce Alphonso: four healthy children, a six-bedroom house, a Mercedes in the driveway. But a few decades ago, life was much bleaker. They were both surviving day to day in Guyana, their families crowded into small cottages without indoor plumbing. Mervyn's father had died when he was 13, casting the youngster into the work force as a messenger who also attended school; Joyce studied furiously in the hopes of getting a job abroad.

Emigration was the only way out--Mervyn left for the States and worked in hospital maintenance before joining a bank, while Joyce got a job as a nurse in Britain, then in New York State. The couple met and married in Albany, N.Y., and finally settled in Springboro, Ohio, where Mervyn's banking career flourished. He worked his way up the ladder to become the president of KeyBank's Dayton office. Joyce worked at local hospitals and raised the children.

When they retired and their kids left home, the couple, always active volunteers, felt dutybound to do even more. "Coming to the U.S. and [having the chance] to capitalize on so many opportunities, we always had the feeling that we'd been given so much blessing, and there was only one reason why--to share with the less fortunate," says Mervyn.

After thorough research and long family talks, the Alphonsos joined the Peace Corps. They shuttered their house and prepared to return to their native land: Guyana. Only this time around, they would be teaching life skills and preventive health care to a downtrodden population that they knew all too well.

It has been more than four decades since John F. Kennedy famously exhorted a generation of young people to "serve our country around the globe," but for many that message is still as fresh as the day it was first uttered. In spite of the rough conditions, travel advisories and the war on terrorism, scores of older Americans are uprooting their lives to help needy nations improve their living conditions. Some journey to dangerous spots like Liberia and Afghanistan, but most seek adventure in relatively safe regions of the world.

Baby boomers seem to be particularly eager to start a challenging new life abroad. The International Executive Service Corps (I.E.S.C.), which matches executives with business-development work abroad, has watched the average age of its participants drop from 68 in the mid-1990s to about 53. Other organizations, like WorldTeach, report increased interest from the retired population.

Gary Myers, 49, isn't a thrill seeker, but this past summer he leaped at the chance to travel to civil war--engulfed Liberia. Myers, who was a surgeon in Oklahoma, had grown frustrated with American medicine's commercialism. With his kids grown and some money saved, he volunteered with Medecins sans Frontieres, which placed him in Liberia. Seeing children with machine guns at the Monrovia airport, "I really thought I was flying into hell," he says. He worked hard, ignoring the mortar fire at sunrise and sunset as patients with serious gunshot wounds stumbled in. Whereas in the U.S. he would have taken care of 10 patients a day, here he was treating as many as 80. "This is a way for me to use all these things I learned and practice a more pure [form of medicine], the way I had intended to in med school," he says.
