(CNN) - It was 2002 in the Philippines, and American business traveler John Drake was presented with a disgusting offer.
He says a pimp offered him a four-year-old girl for sex "for about 25 bucks".
Drake returned home to Jackson, Michigan, but couldn’t forget the heart-breaking and disturbing scenes of child exploitation.
So, aged 58, he retired from his job as senior vice president of human resources for CMS Energy and Consumers Energy, where he'd worked for 32 years, and began a new phase of his life.
