good luck.
my mom's parents both died from emphyzima? her mom never smoked, she died from second hand smoke from her husband 2 years after he died. my mom has it now at 60. already sucking on oxygen a few times a day because her lungs cant pull enough out of the air. she has less than a hand full of years left. the oxygen itself will destroy what is left of her lungs with continued use. it is like taking poison to help with an injury that wold kill you now if you didnt take it.
thats two generations dying from the same stupidity.
really, good luck. your life depends on it.
