USC and the RAND corporation are doing a study of randomly selected homeless men on Skid Row in downtown Los Angeles. We're talking to them about their health, sexual behaviors and attitudes towards women. I do a 90 minute interview with my RAND-issue laptop and pay them $30 at the end. Amazingly resilient humans live down there. The questions asked are amazingly personal, yet every single one of them can't wait to tell someone... something.
