Faced with a threat or uncertainty, you have two options: #1. It is what it is. I can't do much about it. I will wait and see what happens. Or worse, I will let my fear paralyze me. #2. I don't accept inaction. I can do a lot. I won't let fear grip me, will take charge, and maximize my chances of defeating this threat. I like the second option much better. I believe one of the most important things you and I can do today is to bolster our resilience, particularly immune resilience. A strong and intelligent immune system will not only help you better face today's challenges, but it will make you stronger for every future threat that might knock at your door. This book shares the science and art of building your immune resilience.
