When I was nine years old, I was the sickest I could ever remember: horrible sore throat, feverish, sick to my stomach. I felt like my body had been buried in the back of a garbage truck and obliterated into a crumble of mush. Soon after I came down with the symptoms, the family doctor gave me a shot. Within hours, I felt better. I felt good. I felt like myself. I know that I was only nine, but I can tell you very clearly that this was the moment I knew I wanted to be doctor. My little self said, “If I could help people feel better and make sick people healthy, wow, that’s what I want to do!” And I’ve never strayed from that goal: helping people get healthy to live life to its fullest.And that’s what my newest book, This Is Your Do-Over is about: helping you lose weight, live your passion, thrive in your relationships, and jump into life with energy and vitality – not just for more years, but for younger and fuller ones. I’ll take you through a mixture of information, strategies, inspirational stories, and hard data to give you all the essentials for taking control of your body and your health – no matter your genes, past health mistakes, or the number of times you've tried to tackle your health and failed. It’s time to forgive yourself. Living a vital life starts now: This Is Your Do-Over.MICHAEL F.
