We can define ageism as the existence of negative stereotypes, prejudices and discrimination against people due to their age. It has been pointed out as the third form of discrimination, after racism and sexism.

What does that mean?
Aging is equal to an unhappy stage, of loss of competence, independence, physical and psychological well-being.

Aging equals loss of power and control.

Aging equals frailty, weakness and dependence.

Aging as an essentially negative process of deterioration.
