Health care is a major source of illness deaths for the United States.

And the top five killers are all related to chronic illness.

The top five are respiratory diseases (including pneumonia and bronchitis), obesity, cancer, heart disease and stroke.

The list is made up of diseases that have been studied in the past.

But how does that translate to the future?

Health care and chronic disease is an incredibly complex area, and not one that has been studied enough to know if it will continue to grow or decline.

There are a few factors that may explain why chronic diseases like pneumonia, bronchial pneumonia, or heart disease are on the rise.

Researchers are still learning more about what causes them.

We know that the genes that make these diseases appear in more than one part of the body, so it’s not just one or two genes.

There may also be multiple copies of genes for the same disease.

So, if we look at a patient, we might see a gene that is not only in the lungs but also in other parts of the brain.

The brain can have several copies of the gene that are related to inflammation and a variety of other health problems.

It’s difficult to say exactly what is causing these chronic diseases, but some researchers think that it may be related to stress.

In a 2014 study published in PLOS Genetics, researchers found that chronic lung disease was linked to a variety, and some were related to high levels of stress.

They speculate that the stressors could be driving the rise in chronic disease.

But what about other health conditions?

We know more about cancer, which is a leading cause of death in the United Sates, and it’s also increasing.

Cancer rates have doubled in the last 50 years, and the disease has become a big contributor to the overall health care bill.

Some researchers think the increased rates are linked to the use of more cancer drugs.

But we know that there are also many other conditions that are being attributed to environmental factors.

So we’re still learning a lot about how chronic diseases are linked.

What do you think?

Does this mean chronic diseases will become more prevalent and more costly?

What are the major threats that chronic disease could pose to the American economy?
