Smoking makes you look sophisticated until it makes you look like a mummy.
It's a well-known fact that smoking causes your face to age prematurely. But knowing that and seeing it are two different things, as three smokers found when they volunteered to have BuzzFeed simulate what they'd look like 30 smoke-filled years in the future. Yellow teeth, wrinkles, sallow skin… these are what they saw when they looked in a mirror.
Needless to say, they were shocked, and considerably more motivated to quit smoking. It would be great if this service could be done for all smokers. After all, everyone knows smoking can kill them, but that's nothing next to the possibility of not being hot anymore.
