Its like this, people can smoke in their 20's with very little damage. Although put head to head someone that started smoking at the age of 19, and another person who started smoking at the age of 39 years. Both dudes are now 50, both probably have just as bad of damage and just as likely to have health problems at 50 even though one started at 19 years and the other at 39. The smoking done in the 40's and beyond is where ALL the damage to lungs and health is done.
