Aging: Drawing a Map for the Future

I live on a short street in a small town, Hastings-on-Hudson, some fifteen miles up the Hudson River from New York City. Over the past decade a number of families have moved in, with about sixteen children among them. More than a bit housebound now because of old age and watching them romping about, I try to imagine what their world will be like when they have reached my present age, some eighty years from now. But I have a problem. I just can't imagine it. The demographic changes now appearing on the horizon will force unforeseeable changes. What would it have been like in 1930, when I was born, if someone then had to project the future of aging? They could not have guessed.Some momentous changes are now emerging, and they are bound to change the aging picture. What's being done to respond to those growing pressures?
