Treating the sick in Bamburi, KenyavTreating the sick in Bamburi, Kenya

"During our two-week trip, we dug the foundation for a school. We also set up a one-day clinic, and we saw over 1,000 people. (I'm a physician's assistant.) One of our first cases was a boy whose throat and stomach hurt. He had been eating sand and rocks because his body craved various minerals. We were able to educate him -- and many others -- on the importance of eating meat and leafy greens whenever possible. And by questioning different people, we were able to identify a specific water hole as being home to a parasite, and we told everyone to avoid it. For me, the best part was leaving something sustainable, not just a quick fix like a Band-Aid or aspirin." -- Erik Zenger, 39, Salt Lake City, Utah
