The wear and tear theory of aging believes that the effects of aging are caused by damage done to cells and body systems over time. Once they wear out‚ they can no longer function correctly.

The organs‚ liver‚ stomach‚ kidneys‚ skin and so on are worn down by toxins in our diet and in the environment. The excessive consumption of fat‚ sugar

The immunological theory of aging‚ or immunosenescence‚ advances the idea that the immune system is programmed to decline over time. This programmed deterioration in immune system results in an increased vulnerability to infection disease‚ and thus leads to aging and death.

Routine activity theory is a sub-field of rational choice[->0] and criminology[->1]‚ developed by Marcus Felson[->2] and Lawrence E. Cohen[->3]. Routine activity theory says that crime[->4] is normal and depends on the opportunities available. If a target is not protected enough‚ and if the reward is worth it‚ crime will happen.
