I was traveling over the 4th of July here in the US and had written this article in advance, but something got stuck and it did not publish. Technology!

Changes in the Human Body. –The human body is in a constant state of change. In the midst of life there is death. The blood discs die and new ones are born into life. Every act of life is destructive as well as constructive. Not a thought can be evolved but numerous brain cells die; not a wink of an eye, a smell of a lovely rose, nor a muscular movement, but results in the death of some part of the machinery involved. Every process of life is a process of death. The scales of the epidermis are constantly falling off to be replaced by fresh cells from beneath, and it is on the continuance of this interchange that our life, health and vigor depends. The more rapidly this change goes on, and fresh, vigorous, healthy tissues take the place of the old lifeless ones, the more elasticity, buoyancy and strength we possess — the more healthy and robust we become.

To a layman most of that last paragraph sounded like nonsense. Yes, cells do die and more cells are created throughout the human body. the author describes in a way that makes it sound like birth is given to the cells by other cells. I think the part the Mesa sound rather ludicrous is based on the author’s assumption that there is a cause-and-effect. When you move a muscle according to the author’s reasoning, that movement kills a muscle cell and births another muscle cell at the same time. Cells may be creating and dined at the same time but I don’t believe it’s from the exertion or the motion. That seems to be a fallacy in the logic from the statement.
