List of largest lakes of the United States by area

Lake Superior is not only the largest lake in the United States, it is also the largest freshwater lake in the world by surface area. The greatest of the Great Lakes has a surface area of 31,700 square miles (82,100 square kilometers) and a volume of 2,900 cubic miles (12,000 cubic kilometers).

Technically yes, relative to an observer on Earth, a person at higher altitudes will age faster.

Acute exposure to high altitude can affect the cardiovascular system by decreasing oxygen in the blood (acute hypoxia). It also increases demand on the heart, adrenaline release and pulmonary artery pressures.

With increasing altitude, systemic vascular resistance rises, elevating heart rate and blood pressure; likewise, pulmonary vasoconstriction produces pulmonary hypertension especially during exercise.

For patients with episodes of atrial fibrillation, all the usual stressors of high altitude may (or may not) precipitate a recurrence (paroxysmal atrial fibrillation). Patients tolerate altitude changes better if they are gradual and if a couple of days of restful adaptation is allowed before vigorous activities.

Summary: Researchers have found that people living at higher altitudes have a lower chance of dying from heart disease and live longer.

When you’re mountain climbing, hiking, driving, or doing any other activity at a high altitude, your body may not get enough oxygen. The lack of oxygen can cause altitude sickness. Altitude sickness generally occurs at altitudes of 8,000 feet and above. People who aren’t accustomed to these heights are most vulnerable.

When you travel somewhere at a much higher altitude, low oxygen levels can cause trouble. In Colorado, these early symptoms of altitude sickness are usually all that occurs. More serious symptoms, such as mental confusion, trouble walking, and chronic shortness of breath, tend to occur only at even higher elevations.

Above 28,000 to 30,000 feet with extra oxygen under pressure — normal consciousness and life can be sustained to 50,000 feet. Above 50,000 feet with any form of oxygen — sustained human life is not possible without a pressure suit like astronauts wear.
