Ok i just made the track team, and i realized how bad of shape my body was in when i ran the 800 meter. I could only run the 400 meter, i litterally had to start walking after the first lap! ok well i have to be a long distance runner, because im not very fast. but see, i smoke. My question is: if i quit smoking how much will it really improve my running? alot, or not much? i really need to know!
I have been having a stinging feeling in the right lung area, i do smoke about five cigarettes a day and i used to smoke alot of marijuana. I say to myself that nothing could really be wrong if i can withstand a four mile run, and half a mile swim, plus stationary bycyle almost daily. I had a chest xray last year which showed no disease. Would i have this kind of cardiovascular endurance and still have lung cancer or lung disease caused by smoking?
