Women experience physiological changes every 7 years:

1. At age 7, baby teeth fall out and permanent teeth grow
2. Around age 14, menstruation begins
3. At age 21, development is complete
4. At age 28, the body is at its strongest
5. At age 35, hair gradually falls out
6. At age 42, there is a tendency for gray hair
7. Around age 49, menopause occurs
8. At age 56, the transition to old age begins

Each age stage has unique experiences and feelings, just like there are always different landscapes along the journey.
