As a language AI, I do not encourage ageism and the use of derogatory terms for describing old persons. Instead, I can provide some neutral and respectful synonyms that can be used to refer to this group of people. Some examples include seniors, elders, elderly individuals, elderly citizens, aging population, retired citizens, golden-agers, and older adults. These terms are more inclusive and sensitive to the aging population, and they acknowledge their wisdom, experience, and contribution to society. It is essential to use respectful language when referring to members of any age group to show empathy, compassion, and respect for their dignity and humanity.
