Achronic problem lasts for a short period of time. true or false?

That statement is False

In order for a problem to be categorized as 'chronic' , it need to last for a long period of time

For example when you smoke, you will leave a small amount of chemical in your lung. If you only do it once, that chemical will eventually leave your lounge and it became as good as new

But if you smoke regularly, it will slowly accumulated and one day it create a chronic problem for your lounge
