My parents are life smokers, and are not likely to quit anytime soon sadly. What bugs me the most if having to breath in theit second-hand smoke. I mean, it's not like I sit there next to them and inhale it purposely, it's just sometimes when I walk past, I get an accidental breath of their smoke. They smoke outside away from me but I still manage to get a wiff every now and then. I hate thinking that it's potentially damaging my lungs, harming my on field fitness etc. Is there something to worry about here? Should I TRY and get them to smoke somewhere further away from where I walk about at home (downstairs storage room, backyard etc.?).
