Maybe that's because they are low-cost.
Often the neighborhood provides the infrastructure which doesn't require you own a car.
And there are extra safety measures such as a security guard in the evening.
I am pleased as punch in my little piece of heaven in the north part of Tucson, Arizona.
Given the proliferation of us over-50 in this development, those few under-50 tend to stand out. One had been a Generation Xer I'll call Peter, to protect his family. On a Saturday morning about 10 A.M., very near Christmas, the EMTs came to his door, which is right next to mine. They carried him out. His color was gray. He was unconscious. Shocked, I just stood there.
His two pumpkin-colored cats peered out his window. I went to the property manager. I wasn't sure if he had had his family call 911 or he had done that himself. It turned out to be the latter. "Someone has to take care of the cats. Please let him family know what happened, if they don't already." That's what I told the complex's powers-that-be.
Long story short, his niece came to give the cats food and water. She asked me what had happened. That evening his sister came to take the cats to her house. "He has a 50-50 chance of making it. He can't breathe on his own." That's what she told me. Her body language and facial expressions blared, "Back off."
He died. The whole complex is reeling. His life had started an upward trajectory. After a period of unemployment he was hired into a business which was too busy. He got lots of overtime. He was downsizing the remaining $17,000 in student loans.
I have a hunch that shock became the platform for anger for the sister. When she came to clear out his place she put herself behind a communications moat and drawbridge. No details were provided. But, they wouldn't have helped much, would they.
This is a classic "For Whom The Bell Tolls." If he could leave planet earth so unexpectedly, so can we.
