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 asks about theories of aging, specifically identifying one that relates to the immune system's differentiation ability. This involves understanding various aging theories and their implications.

More Information

The autoimmune theory suggests that the aging process results from the immune system mistakenly attacking the body's own tissues, due to its failure to differentiate between self and non-self antigens.

Tips

A common confusion is mixing it with immunosenescence, which refers to broader age-related decline in immune function.
