Today humans are suffering from so many diseases that knowing the reason of each one of them is getting more and more difficult over time. No one can say when and how a disease would arrest you in its grip. The easier it is getting to become a victim of a disease, the difficult it is becoming to know the reasons of the disease.
Even the disease you are talking about, that is, chronic obstructive disease, may not be known to many here. The reason of chronic obstructive disease is
smoking, and the smoke cigarettes produce. It is a very dangerous kind of heart disease.

If you smoke, or anyone who is often beside you smoke, please know that you are vulnerable to chronic obstructive disease. Children are more prone to this disease. So, if you smoke, it’s not only harmful for yourself, but also for your family.
