Don't smoke and never did. My grandmother was able to quit after smoking for 30 years. My mother in law quit after smoking for 40 years. My grandfather didn't quit until he was bed ridden and on oxygen. He's dead. Seeing the way my grandfather suffered and died was enough to keep me from ever trying cigarettes. Smoking a pack a day is holding you back and is slowly killing you.

My mother in law who quit last year after decades of smoking was barely able to walk across a room without being short of breath. Every cold she got would put her in the hospital. Fast forward a year. She walks on the treadmill for an hour a day 5 days a week. She can keep up with her grandkids and doesn't get out of breath during normal activities. She gets a cold and just feels miserable like the rest of us instead of nearly dying. The transformation from diseased to healthy is actually pretty quick. She was much improved after just 4 months. You are young, quit now before you really screw yourself up.
