Most cases of chest pain don't signal heart problems. While chest discomfort of any kind should never be ignored, many conditions can trigger it. These include gastroesophageal reflux disease, gallstones, asthma, ulcers, anxiety, COVID, esophagus spasms, costochondritis, pulmonary embolism, pleurisy, aortic dissection, and pericarditis. Chest pain is likely to be unrelated to the heart if it's brief, triggered by eating, doesn't worsen with exercise, occurs only with movement, coughing, or breathing deeply, or it's localized to one spot.

Thousands of miles of veins throughout the body bring blood to the lungs to pick up oxygen and nutrients, and get rid of carbon dioxide before returning to the heart to be pumped out again. How do veins work, what problems can occur, and how can you keep these vital blood vessels healthy?

The human body has excess capacity — that is, our organs have more reserve than most of us will ever need. Why are we built with this natural redundancy? And which body parts can safely fail or be removed without impairing health?
