Chronic illness affects nearly 50 percent of the population. By the year 2025, it is estimated that chronic illness will affect some 164 million Americans. Some of the most common are heart disease, diabetes, cancer, and asthma, but that list is by no means exhaustive. Arthritis, lupus, multiple sclerosis, Crohn’s disease, colitis, epilepsy, and thousands of other diseases cause ongoing symptoms and are treatable but not curable.
