One important area is social connections. After you pass 50 years of age the people you're close to begin to die off or become noncommunicative at an ever-growing rate. Health issues begin to interfere increasingly with opportunities to make new friends--there are increasing numbers of activities that you simply can't do anymore. Isolation increasingly becomes a problem, and isolation is a serious health hazard for older people, affecting mental health and posing a hazard to physical health. Platforms that make it easier for older people to stay in touch with one another, to meet new people safely, and to develop networks of trust and assistance could make a huge difference in the quality of people's lives.
