回答: Did he smoke? If so, how much? Did he exercise? If so, how much? 由 HunHunSheng 于 2006-2-14, 10:18:55:
Heard from radio of a study, fewer than 5 a day has about 50% more chance to get lung cancer. The percentage goes faster when smoke more. It is about 5 times more chance if smoke 2 packs a day. Exercise has no obvious help.
