Life cycle of Humans

• The first stage in the human life cycle is the embryo, which is the fertilized egg and sperm that is implanted in the mother's womb.
• The embryo starts to grow into a fetus for nine months until it is ready to be born.
• Once the baby is born, the young stage of the human life cycle begins.
• During the baby stage, which lasts from birth to age one, babies can talk, they can cry to communicate their needs, and they learn to crawl, walk, reach out, and explore things around them.
• From the baby stage, the human will develop and grow into the childhood stage.
• The challenge stage of the childhood stage lasts from 2 to 11 years old, during which the child can independently interact physically and verbally with others at school.
• During the adolescent stage, which lasts from 12 to 18 years old, the physical and sexual maturation of humans are significantly developed, and they are more independent to explore different skills, ideas, and new rules.
• From the adolescent stage, the human will develop and grow into middle age.
• The middle age is the beginning of the adult stage, which lasts from 30 to 50 years old, during which adults are working hard, have influence and commitment to their spouses, children, and community.
• Physical changes that signal aging are also happening during the middle age adult stage.
• From the middle age adult stage, the human will develop and grow into old age.
• The old age lasts from 60 years and older, during which adults have less physical activity, work increases, physical health problems increase, and their ability to fight illnesses decreases.
• If a human in the adult state reproduces, the life cycle will be repeated again.
