Glad you liked it, Otis.
It's amazing how many people are unaware and even shocked to realize that they have within their own control the ability to reverse myopia and improve their vision. The concept of hormesis -- making things more difficult so that the body adjusts to make things easier -- is often hard to grasp, but once people get it, I often hear the "aha" insight reaction: It makes so much sense and explains why their reliance on glasses over the years has made things worse, not better.
Appreciating how hormesis applies in many different areas -- not just eyesight improvement, but also strengthening of muscles, metabolism, immunity and psychological resilience -- is a powerful way to instill confidence that we are adaptive organisms with the power to change and improve our health in many ways.
