Both of these have already worked in Hospital Diospi Suyana last year. Now in 2008 they will again sacrifice their summer holidays to travel to Peru. In September we are expecting Dr. Matthias Stefani and in October Dr. Hagen Bruder. Normally people who work hard in their free time are called “workaholics”. However, we are glad about the return of our friends and will “keep the knives sharpened” for them!
