One of the best exercises is walking. Cardiologists suggest that each of us walk 10,000 steps per day. Assume each step is 0.5 meters or 19.7 inches. Then 10,000 steps would cover 5,000 meters or 3.11 miles. But studies find that the average American (from age 4 and up) takes only 2,000 steps/day or 1 kilometer.
Your tongue offers an early warning system
Last week’s column began a review of “The Wonders Inside THE HUMAN BODY,” a Silver Dolphin Book by Jan Strandling published in 2009. Following are more nuggets of information culled from “THE HUMAN BODY.” One quarter of all of your bones are in your feet, each foot having 26 bones, 33 joints and 19 muscles. The most sensitive parts of your body are your hands, lips, tongue, feet and fingertips. Each fingertip has 100 touch receptors. The most numerous pain receptors are the free nerve endings. There are free nerve endings around each your hair follicles. So it’s not surprising that when you pull on someone’s hair, it can be quite painful.
Ever wonder what’s going on inside you?

Earth’s climate keeps changing, but why?
Earth’s climate has been subject to change, long before humans walked the Earth. Why should the climate change?
The Earth is a dynamic planet, subject to the shifting of the crustal plates (which can lead to increased volcanic eruptions), the advance and retreat of glaciers and changes in the Earth’s motion about the sun (Earth’s axial tilt and the varying ovalness of the Earth’s orbit).
