Aging isn’t a problem to be solved. Or a disease to be cured. Or something icky that old people do. It’s how we move through life, and more of us are doing more of it than ever before in human history. What stands between us and making the most of these longer lives? Ageism: judging, stereotyping, and discriminating against people on the basis of how old we think they are. Solve for ageism and we also address sexism (aging is gendered), ableism (disability is stigmatized), and racism (which denies multitudes the chance to age at all). So I’ve written a book. I blog about it. I led the team that developed Old School, a clearinghouse of anti-ageism resources. I am the voice of Yo, Is This Ageist? (Go ahead, ask me.) I speak widely. All efforts to help catalyze a grassroots movement to raise awareness of ageism and how to dismantle it.
