Introduction to boarding the health express at the age of 40

Men around the age of 40 are at a critical stage in their lives. If male friends can grasp their health well at this critical stage, they will not get sick before the age of 60, and will not get old before the age of 80, and they will easily live to 100.

This book starts with psychology, marriage, sex, diet, exercise and other aspects, and provides practical and effective healthy living programs for men around 40 years old.

This book emphasizes paying more attention to mental health and diet health while paying attention to physical health, so as to lay a solid foundation for the happiness of yourself and your family.
