It's really unfortunate that so many people live in places where this is the case. One amazing thing that you notice when you walk around places that are walkable and have great transit is how mobile a lot of the old people you see around are. There's a strong correlation between more walking and reduced all-cause mortality (not just for older people but even for the middle-aged), so living somewhere that encourages getting around more on foot instead of by car just seems to automatically keep people moving for longer (as I understand it, past a certain age losing muscle mass is very difficult to come back from so maintaining it for as long as possible is key). Even when walking gets too difficult, these places tend to be way better for things like mobility scooters because you can actually get places worth visiting safely, within the range of the battery and in an acceptable amount of time.
