Hopefully the children will be exercised before the constriction sets in. They are blaming genes and asthmatic patents. Bet you take a close look at the stress levels and nutrition and you will learn more than the gene pool ever could say. I hate it when they cop out like that. For the inner city poor I would bet on the nutrition and stress again.
Poor parents have even fewer options.
The problem with the stress levels as a source of the problem is that air can be cleaned, nutrition can be changed, even rampant outgassing of pressed glued wood and toxic house cleaners and all the things covered in Debra D's books will give you more insight on all of this. It just stays to overdrive the nervous system just as a car would if it revved the engine to maximum 6000 RPM while at a stop light or in the garage. . As long as they blame genes or the environment they will overlook the damage that has already been done and continue to drug and cut to make up for their lack of understanding. Without understanding that the breathing need be looked in to, we will continue to try and arrest the symptom instead of the cause. Immune system failure is caused largely by thymus and spleen malfunction.
