I have been an on and off smoker for awhile. I quit for quite sometime and then somehow start smoking again. I personally don't like it because it costs to much and it makes you smell bad. Those are the primary reasons for me. However, I am in great shape, I run 3-5 miles a day, lift weights, etc. I would like to permanently kick the smoking habit simply because it doesn't help my mission to find a liberty minded girlfriend...which is entirely challenging in itself.
