Tbf, my great aunt chain smokes 40 a day. As she got older and had health problems (mid 80s), her family tried getting her to quit, they took her to the Dr's to discuss it and the Dr flat out told them getting her to quit will be what kills her, she's gone too long to change now, just let her carry on.

My Mom finally quit smoking after many attempts and the stress of it triggered a shingles attack that lasted the rest of her life.
