Which theory suggests that aging is caused by the body's immune system losing its ability to differentiate between self and non-self?

Understand the Problem

The question is asking which theory explains that aging results from the immune system's inability to distinguish between self and non-self. It presents multiple theories related to aging and is looking for the correct one.

More Information

The autoimmune aspect where the immune system becomes less effective at distinguishing self from non-self fits within the broader Immunologic Theory of aging.

Tips

A common mistake is confusing the Immunologic and Autoimmune theories, as both involve immune function.
