If we compare life to a circle in a geometric figure, on a circle that has already been drawn, it is difficult to find where the starting point is and where it ends, but you have to find out how long the radius is. It is relatively easy. A circle has a radius, and a life has a radius. The width, thickness, and severity of life are determined by your life radius. The larger the life radius, the greater the space of your life. What does this text mean? ["It's not uncommon for young people to live far better than older people.", 'Although life is a variable thing, it is also measurable.', 'There is value in life, and it is not worth it the longer you live.', 'To measure life, you should first measure what you think, what you say, what you do, what you do.']
