Dr. John Tickell is an Australian doctor, businessman, author, former athlete (played footy with Hawthorn) and speaker. I’ve known John for a long time and in many ways, he has been ahead of the (health) curve for years in terms of his thinking, writing, researching and his approach to treatment, recovery and clinical management. I will warn you, there are a few dad-jokes in this chat, a little background noise (for about ten minutes) and possibly a little, er.. direct-ness but at 77, the good Doc is still working, writing, researching, inspiring and educating the masses. His new book is called ‘Your Best Immunity’ (Wilkinson Publishing). Enjoy.
