Im a smoker so ignore if you wish
I aint preacher wether you do or not but it was described to me once like this (not that it did much good, I did quit for 3 years but started again during my divorce)
Imagine driving a formula one car with a prestine engine but using diesel!
As you train the toxins from ciggies are pushed around the body harder, so in some repects could do more harm. Obvioulsy if you get a smoking related illness then the fitter you are the better, but some of it rings true.
At the end of the day fitness depends on lungs and their efficacy in transfering oxygen to the blood and CO2 out of it, if you clod your lungs up with smoke and tar then that efficacy is reduced. Your blood is also clogged up with toxins and its your blood that feeds the muscles and transports waste away.
When your young your body copes, but believe me doing the fan today I suffered and i blame the ciggies!
Will I quit again............writing this and realising the shite Im putting into my body you bet ya!!!!!!!!!!!!!!
I dont agree with the 5% quoted , if you loose a lung through smoking your going to suffer by more than 5%
