What Happens When We Age?

By Rebecca Woodbury Med PhD

All living things age, and aging begins inside the cells. Cells, atoms, and molecules are described.] As we grow, old cells are replaced as the body by makes new molecules used by cells to divide and make new cells. As we age, cells start to divide more slowly and cannot make new cells as quickly. After many years, some cells stop dividing, making it harder to fix small damages. DNA gives instructions to cells DNA is described]. Over time, DNA's instructions can become less clear, leading cells to make mistakes and slowing down repair. Small bits of wear and tear can be cumulative, leading to joint pain, weaker eyesight, and changes in skin, hair, and muscles. Aging is a natural part of life that can't be stopped, but taking care of the body helps cells do their best to continue to work well.
