How smoking affects our skin 

Smoking? You must be joking!
Did you know that there’s a way to tell if someone’s a smoker just by looking at them? Smokers typically have certain telltale physical signs that you can spot if you look closely, like:
1. Yellowing front teeth
2. Yellow stained nails and fingers
3. Wrinkles around the mouth (smokers lines)
4. Bluish-black coloured lips
5. Elderly people, who typically have white hair also experience yellow staining on their moustaches due to continued exposure to smoke
In a study done by observing a set of twins, it was found that the twin who was a chronic smoker had visible signs of skin damage such as premature wrinkling and sagging skin and could easily be told apart from her twin. However, the physical damage caused by smoking is far less deadlier than the havoc it causes internally. Cancer, heart disease, lung disease, bronchitis, emphysema, increased susceptibility to infections and tuberculosis are just a few of the consequences of smoking. Maybe those anti-smoking ads that are screened before every movie (and Mukesh) made some points!
