People with cancer, diabetes and heart disease mistakenly think exercise is unsafe

[Northerner]

For people with a chronic health condition, exercise might seem like a low priority, if not something to avoid altogether. Many people with such illnesses as cancer, diabetes and heart disease mistakenly think that exercise is unsafe for them. But ongoing research is making the opposite case, showing again and again that regular activity is not only safe for most people with chronic illnesses but can actually boost vigor, increase longevity and reverse some symptoms of many conditions. In some cases, it can even reverse the course of disease ? for example, by reducing coronary artery plaque. For people with a chronic illness, here are some questions and answers about getting and staying active.

How do I start?
Even if you don?t have a chronic illness, it can be hard to get started on an exercise routine. For example, about half of very old adults cite muscle and joint pain or weakness as reasons for not exercising, regardless of their overall health.
