Groups that connect elders and teens — both in real life and online — have a new sense of urgency in the loneliness epidemic.

Almost 40 percent of caregivers of older adults are men, and a third of that group is Black. But African American men face some issues other guys don't.

Assumptions that older people are one big, frail, homogenous group can lead to problems, says the author of Elderhood.

Fewer than half of older adults who need mental health care or treatment for substance abuse get it. Many therapists don't feel qualified to treat older people, and insurance coverage is spotty, too.

The director general is asking for a halt for at least two months. His hope is to use all available doses to vaccinate 10% of the population in every country by the end of September.
