Meta-Age is the final book in a trilogy covering Wayne Lèal's midlife journey. The first book, 20-21, is about developing the discipline to make exercise an intrinsic behaviour such as brushing your teeth. The second, Lone Wolf, introduces the concept of becoming a 'Super-Ager' - one who is biologically younger than their chronological age. Meta-Age, the final book in the trilogy, marks Wayne's midlife transition and the creation of a new life stage - 'Meta-Age: a midlife extension, not old age'. All health and fitness roads lead to Meta-Age, that is, self-awareness of physical, mental, and social expectations beyond midlife. The desire to defy age is as ancient as human history. We cannot stop the natural intrinsic ageing process, but by taking some preventive actions, we can influence some factors of that process. The Meta-Age philosophy focuses on an extension of midlife, with a short old age, to write a new narrative of ageing as it could - and should - be.
