“People lose fifty million skin cells every day. The cells get scraped off and turn into invisible dust, and disappear into the air. Maybe we are nothing but skin cells as far as the world is concerned.”

“If wishes were held on the skin and swiped by raindrops, then emotions were freeloading off the cells that made up their space. The only offering these cells ever entertained was truth, painful and raw.”

“Every seven years our bodies change, every cell. Every seven years, we disappear.”

“When we entered the material world, God lent us a body to act as a vessel and encase our souls. Our body is our temple and, miraculously, it is in a state of constant renewal.Fat cells are replaced at the rate of 10% each year. Skin cells are renewed every two to four weeks. Our 9,000 taste buds are renewed every 10-14 days. Our skeleton is renewed every two years. Every day billions of cells replace the ones that came before them. We are in this miracle of creation and renewal every second of our lives… unless we mess up that renewal. God not only gave us a constantly renewing body, but he also provided a profoundly rich, diverse and constantly-renewing food supply.”

“All cells come from cells. Every cell is born of a previous cell, which was born of a previous cell. Life comes from life. Life begets life begets life begets life.”

“When cells are no longer needed, they die with what can only be called great dignity. They take down all the struts and buttresses that hold them together and quietly devour their component parts. The process is known as apoptosis or programmed cell death. Every day billions of your cells die for your benefit and billions of others clean up the mess. Cells can also die violently- for instance, when infected- but mostly they die because they are told to. Indeed, if not told to live- if not given some kind of active instruction from another cell- cells automatically kill themselves. Cells need a lot of reassurance. When, as occasionally happens, a cell fails to expire in the prescribed manner, but rather begins to divide and proliferate wildly, we call the result cancer. Cancer cells are really just confused cells. Cells make this mistake fairly regularly, but the body has elaborate mechanisms for dealing with it. It is only very rarely that the process spirals out of control. On average, humans suffer one fatal malignancy for each 100 million billion cell divisions. Cancer is bad luck in every possible sense of the term.”
