Smoking Tobbaco is well-known to lead to cancers of the mouth, lungs and throat as well as stimulate many other diseases including simple asthma.
Decades of research have proved this and led to further discoveries into the toxic side of smoking.
Now, it is often said that smoking 20 a day will dramatically decrease the length of your life.
But, hey, there's a 90 year old lady who has been smoking tobacco since she was 20 years old.
