The boundary between self and non-self refers to the distinction between an individual's own body and the external environment. This boundary is maintained by the immune system, which is responsible for recognizing and defending against foreign invaders such as bacteria, viruses, and other pathogens. The immune system is able to distinguish between self and non-self through the recognition of specific molecules and antigens. When this boundary is breached, the immune system mounts a response to eliminate the foreign invaders and protect the body from harm. **

They are recorded on the balance sheet as liabilities and are deducted from the company's total assets to determine its net worth. Examples of non-self-sufficient assets include leased equipment, intangible assets with limited useful life, and investments in subsidiaries that require additional funding. **
