Some research says that 1 million each year are affected (die) having cardio-pulmonary illness.  What I do is keep a bowl of nutrient pills on the counter as a snack.  Milk thistle, bilberry, vit. c, b complex, L-carnitine, nuts, something with lecithin in it like eggs, and fish oil pills, amino acids complex.  Also something to keep cell walls strong w/sulpher MSM + Glucosamine.  Get some sun.
