The unraveling

Our body’s most basic design feature may hold the key to understanding how our society has become so unraveled.

Will this be life-giving for me?

How can we tell if something is alive?

That’s cool, […]

Marked by Beauty

Imagine, to be marked with such beauty and not even know it…

Don’t Just Stand There, Move

The anatomy and physiology book from which I used to teach college students states, “Biologists have found that all living things share certain basic characteristics, including the following (in this order): responsiveness, growth and differentiation, reproduction, movement (internal or external), metabolism and excretion. By internal movement, they mean the movement of things inside the organism. By […]
