I would ask several questions about early life environment. What was the distance from a major highway/roadway of your childhood home? Did you grow up (pre and/or post pubescent) in a rural area? When first diagnosed, how much walking (outside) did your lifestyle require? (Correlate with distance to highway and urban/rural environments.) How long after diagnosis could you maintain your previous level of walking? Was game (local fish, venison, etc) a part of your diet?
