Dr. Kumar Bahuleyan went from extreme poverty to lavish living as a neurosurgeon. He was born into the poverty of the "untouchable" caste in India. Then he came to America, made millions and owned a Rolls-Royce and five Mercedes Benz cars. Now, completing a full circle, he has returned to his native village, donated his fortune, built a hospital and traded his cars for a bicycle, finding joy in doing so. (Buffalo News)
