A Boston suburb combined its high school and senior center to create a hub for the community. The result has saved space and forged interesting friendships.

More than five million Americans have Alzheimer’s or similar illnesses, and that number is growing as the population ages - without any immediate prospect of a cure, advocacy groups have begun promoting ways to offer people with dementia a comfortable decline instead of imposing on them a medical model of care, which seeks to defer death through escalating interventions. An Arizona nursing home offers new ways to care for people with dementia.

A few adult children have found that the simplest arrangement can be found in an apartment at the same retirement community, as it enables them to care for their elderly parents efficiently.

More retirement and nursing homes are asking college students to move in, an arrangement that benefits everyone. Students stay free of charge in exchange for volunteering to help the seniors.

These days, most rural communities in the U.S. are elderly communities - 15 percent of Wyoming’s population is over 65 and a high percentage of them live on ranches in small towns.

Through the Burbank Senior Artists Colony - a community created by EngAGE - low-income seniors learn how to become artists. The recreational classes hosted by the community keep people feeling phsyically and mentally young, allowing them to focus on recreation instead of financial hardship.

Not all seniors need the various discounts they receive. The Boomerang Giving project allows them to donate back the difference of the discounts on things like movie tickets to a charity of their choice, benefiting not only a community cause but also their own mental and physical health.

The U.S. prison population is aging, which is costly because older inmates need more care. Some states have responded by creating special wards, having the young inmates care for the old, or building nursing homes.

Cities tend to be dangerous and difficult places to live for older residents. A private public partnership in New York is catering to seniors through small changes in the city such as para-transit options and seniors-only hours at public establishments.

Some inner city schools, nonprofits, and businesses in New York lack the staff to make their organizations function for the people they serve. ReServe is a program that links retired professionals with part-time jobs in schools, libraries, hospitals and other city agencies to help fil this gap.
