On nytimes.com, in the Health section. Interesting. Requires motivation and money, but nice to hear that some folks are thinking ahead -- productively.
Reader comments add some different perspectives. Quite a cross-section. Or as my late mother was fond of saying, "It takes all kinds."
Yes, it is nice to age in place, if it is reasonable. And it takes $$$ as professional caregivers will be needed eventually and the monthly cost could be out of reach budget wise.
For myself, I rather sell my current home and move into a 55+ type environment where all that work has already been done. Then if I need more help then a spouse or grown child can handle, move to the Assisted Living section of the community. Yes, expensive, but cheaper than 24/7 professional caregivers unless one has the money.
