Final answer:
Knowing one is dying provides the advantage of planning a personal proper closure, including hospice care and creating living wills or DNR orders, according to individual values and wishes for end-of-life care.
Step-by-step explanation:
An advantage of knowing when one is dying is that the individual can close their lives in a manner consistent with their own ideas of proper dying, as proposed by thanatologists and psychologists like Elizabeth Kübler-Ross. This process, involving the stages of denial, anger, bargaining, depression, and acceptance, can be faced with the autonomy to make personal and informed decisions concerning end-of-life care, including the creation of advance directives like living wills or DNRs. Furthermore, this awareness allows for the possibility of arranging hospice care, to ensure a death with dignity and comfort, potentially in one's own home.
