We are now living through one of the most significant revolutions in human life: the dramatic increase in life expectancy. This revolution, contrary to popular belief, does not simply mean we have gained additional years of old age. Instead, it signifies the emergence of a new stage in human life known as the "Age of Wisdom." This era is qualitatively different from the adulthood that precedes it and the old age that follows. Those who can prepare for this new stage will be able to enjoy an active, wise, and fulfilling life, allowing them to delay old age to a very short period at the end of their lives. This wonderful book offers a practical, thought-provoking, and life-changing read, both for those approaching retirement and for young people who wish to prepare early for this stage. This book is based on Dr. Lanir's lifelong experience studying mental patterns that are no longer useful or appropriate for current reality. He reveals how we can reframe our ways of thinking and our mindset, so that we live our lives according to our "functional age" instead of our "chronological age." The fruit of this long experience is this book, which carries a unique and inspiring message that life in the wisdom years should be full of enjoyment and planning, as a new and honorable journey in the path of personal development.
