As you read this page tremendous changes are taking place both inside and outside your body. This site lets you see the change over time in three areas:

LIFE: Your body is made up of somewhere between 50 and 100 trillion cells. On average you replace your entire body every 7 years. This works out to somewhere between 300,000 and 400,000 cells per second. The heart is the engine for all life. The average adult heart pumps between 1500 and 2000 gallons of blood per day.

PEOPLE: Every second brings more births (4.2) than deaths (1.8) . At current rates we are adding 2.4 additional souls to the planet every second.

MOTION: As we sit on planet Earth we feel stationary. Yet the surface of the Earth revolves at tremendous speeds. At the equator the Earth is spinning at 1038 miles per hour. Along the Chicago, New York, Rome latitude the Earth moves at 783 MPH. You can check your speed here.

We also move around the Sun at 18.5 miles per second or 66,600 miles per hour. Our entire solar system circles the center of the Milky Way at 155 miles per second or 558,000 miles per hour.
