Smoking and copd (chronic obstructive pulmonary disorder)) would need to be known to render any estimate of how many years your life might be shortened. The
conceptConcept dha of lung age, a determination made on the basis of pulmonary function tests (PFTs), may be relevant. The "lung age" is the age of the average person who has an FEV1 equal to that of the individual.
Combining your lung age with the average life expectancy in your family would give you an approximation of the number of years your life might be shortened, based on your current age and your current pulmonary function.
You should collaborate with your doctor on smoking cessation and make every effort to quit now. Quiting can add years to your life and it is never too late to quit, and derive benefit from the quiting, especially at the relative young age of 54.
Good luck.
