caleb has cystic fibrosis. 30,000 americans suffer from the disease which causes thick mucus to build up in the lungs and digestive tract, making it difficult to breathe and make down food. cystic fibrosis patients undergo a rigorous routine including breathe treatment and twice a day they areny a vest that fills with air to help break up mucus in the chest. >> i have to put this on everyday but it's not really tough for me. >> reporter: there is no cure for the disease, but the ocean is a natural treatment. research has shown that salty mist from the water can help break up thick mucus in the lungs and make breathing easier. >> after surfing, i can sit on the beach and take a deep breath. >> reporter: doctors suggest that cystic fibrosis patients living near the coastline take advantage of the health benefits found in the salt water air. >> inhaling high salt-containing liquid into the lungs helps draw fluid out of the issue and create a surface lining that these children would not have. >> the key to learning

what's important is it's not a hundredpercent like it is with simple genetic trait like cystic fibrosis where identical twins, both twins will have the same disorder. here half are discordant or don't share that disease. >> there are other factors playing a role like environmental factors. you see also looking at non-identical twins who are essentially just siblings but yet, they have a higher risk than siblings because they share an environment. we think of complex disease as now having contributions of genome as well as contributions to the environment. it's usually easier finding the genetic factors first and trying to sort out the environment. >> charlie: there are a lot of genes involved here. >> the problems, we know that it's not one gene, we don't know quite how many genes but it's probably a handful of genes but learning in the last several years is that the brain unlike many other organs presents a mutational target. there are so many proteins that contribute to how the brain works. if you disrupt any one of them you might have a sill her outcome. so the different genes will l

particular paragraph, there is a clear mention of children with underlying pulmonary disease, cystic fibrosis, and compromise of any systems -- of immune systems are at high risk. there was another document just six days later that describes the recall of children and infants tylenol directed at the public, but there was no mention of any conditions a child might have like cystic fibrosis that would make them more vulnerable. it makes sense in case you have to go to the doctor to get your medicine, but the doctor would have a chance to convey the hazard to the patient, but this is an over-the-counter drug. apparently, they kept the public out of the loop. about this pattern -- we have a feeling the product was defective that kept it away from public knowledge. they hired phantom contractors who purchased the product but did not inform -- in fact, the contractors were told not to tell store personnel. inform the doctors, do not inform the public. what we have here, i think, is a pattern of concealment. one of the things i am concerned about, with all due respect, your presentation has all the
