Generations United, based in Washington, D.C., focuses on promoting programs that enhance intergenerational cooperation and understanding. One such program is run by the Macklin Intergenerational Institute in Findlay, Ohio, which operates a childcare center within a continuing care retirement community.
Macklin has gotten a lot of press recently for its Xtreme Aging simulations -- sensitivity training programs that offer participants an opportunity to experience the deprivations of aging. Two reports by program participants are here and here.
