Smoking!

We all know that smoking is injurious to health. But we find it difficult to quantify it. Also the observational bias impairs our ability to assess the damage caused by smoking. People who are dead because of smoking are never gonna come and tell us they dies of smoking. Also we do not see them at work place or parties. The people young and old whom we are are the one who smoke and are still attending parties or working!! This erroneously tricks us into a false sense of security. Our brain comes to conclusion that smoking may not be that harmful or that it selectively harms and I am not one of them.
Science/research can help/aid us to see things clearly.
Smoking affects both men and women. The data for females has matured late. A paper published in lancet documents the ill effects well. Without going into the statistics or much into the data, let me give only the conclusion here..

Among UK women, two-thirds of all deaths of smokers in their 50s, 60s, and 70s are caused by smoking; smokers lose at least 10 years of lifespan. Although the hazards of smoking until age 40 years and then stopping are substantial, the hazards of continuing are ten times greater. Stopping before age 40 years (and preferably well before age 40 years) avoids more than 90% of the excess mortality caused by continuing smoking; stopping before age 30 years avoids more than 97% of it.

Wish everyone healthy living!
