Here's a conundrum for you, our whole lives we have been told not to smoke.

I just found out in my epidemiology class that there's a link between parkinson's disease and smoking. There are studies where individuals who are considered "smokers," having a lower incidence rate of having parkinson's disease. Crazy huh? The terrible habit of smoking may actually protect people from a disease of old age. Now as a public health official, I'd like to take a moment and say: STILL DO NOT SMOKE: if you jump off this cliff, it will protect you from getting cancer. False.
