My grandfather died at the age of 87.
His twin brother died at the age of 107.
Both of them used tobacco in moderation.
What I am trying to say here is that whatever we do, we should do in moderation.
Apparently, your family is genetically predisposed to resisting addictive compounds like nicotine.
This does not mean that others are quite so lucky. And the addictive nature of nicotine means that many people are unable to quit and/or smoke in moderation.
