I would really like my old dad to remove his smoking habit (3 packs per day) because it's bad for him and the family ( as per the scientific evidence and statistic ). Why would my old dad pay for something that harms his body? i have no clue .. But i do know this , never underestimate the "force" of money and marketing in combination by the big big corporation .
One of these days , we may find ourselve eating highly addictive food as bad as nuclear device because the corporate sponsored media portrays it as healthy and cool ! ( a bit of exaggeration here

)
Fortunately , my old dad is taking plenty of tea + garlic & traditional herbs daily and that sort of balance back the damage that's done .
