The Human Body



Until a person is about nineteen, the brain continues to grow, adding new cells every year. After that, until the end of life, the brain slowly dies, losing several thousand brain cells every day. After the age of twenty-seven, the body becomes brittle. It is harder to recover from injuries, but much easier to get injured. The muscles lose their ability to stretch. But by far, the worst part of getting old is that we become prone to diseases that seem to accompany aging naturally; heart diseases, cancer, arthritis, strokes.
