One more thing that i can think of is that my brother is only 5 years older then (i am the youngest) and my whole family smoke cigarettes (except for the one that molested me but anyways) we all smoke cigarette and our ages range from me 31 to oldest brother who is 49. NONE of us have much of a breathing problem. one of my brothers 38 has always had asthma. but this brother in question has really bad breathing problems from smoking cigs. he has copd and wears a breathing tank at all time. also when he was a teenager he asked my mom if she was really his mom (she had never told him about this or even thought about it again until recently)
