What are the theories on aging?

There are several error theories of aging: Wear and tear theory asserts that cells and tissues simply wear out. Rate of living theory is the idea that the faster an organism uses oxygen, the shorter it lives. Cross-linking theory states that cross-linked proteins accumulate and slow down the body’s processes.
