Solid Snake: "Yeah, so what?"
Dr. Naomi Hunter: "Didn't you know that cigarettes contain benzopyrene, a chemical that leads to lung cancer? We now know that when benzopyrene enters the body, it changes to benzopyrene diolepoxide and attaches to the receptors on the P53 gene, the gene which causes lung cancer. The BPDE attaches to the P53 gene in three specific locations and causes pre-cancerous changes to the lung tissue."
Solid Snake: "You know a lot about science, but you don't know how good a cigarette tastes in the morning."
