Longevity preparedness is about more than money. The home, the people, technology, and services surrounding it are increasingly part of the retirement security equation.gettyRetirement planning includes choosing where we want to live. Place matters. But who we depend on, who we trust, and the services available to us may ultimately determine whether living where we choose remains possible.For decades, home security meant something relatively simple: keeping someone out. Locks. Alarms. Door and window sensors. A siren if someone crossed a threshold who wasn't supposed to.But longevity is changing what it means to feel secure at home.Aging-In-Place Is More Than Accessibility And Grab BarsThat matters because home is precisely where most of us say we want to be as we grow older. AARP's latest Home and Community Preferences Survey finds that 75% of Americans age 50 and older want to remain in their current homes as they age. Yet 43% believe their homes will require modifications to make that possible.We know the familiar aging-in-place checklist: grab bars, better lighting, fewer stairs, perhaps a first-floor bedroom. Necessary? Certainly. Complete? No.But aging-in-place increasingly requires another infrastructure, one that is far less visible. We might call it an architecture of security.And we aren't particularly prepared. The MIT AgeLab-John Hancock Longevity Preparedness Index, based on a nationally representative survey of more than 1,300 Americans, gives the nation an overall longevity preparedness score of just 60 out of 100. Home preparedness scores only 56. In fact, being ready to live at home well into older age is among the lowest of the eight dimensions measured by the Index. That domain includes whether our homes are accessible, adaptable, connected to needed services, and equipped with technologies that can support independence.MORE FOR YOUIn other words, we may have decided where we want to age without fully preparing for how we will live there.I recently spoke with Laura Finson, Director of Product at Brinks Home, about how the meaning of home security is changing. What began as a conversation about alarms and sensors quickly became a conversation about independence, caregiving, privacy, and trust.“We used to think of home security as protection against intrusion,” Finson told me. “Now, home security is much broader than that.”Today's connected home can do far more than sound an alarm. A motion sensor can indicate that someone is up and moving in the morning. A sensor can tell whether a cabinet has been opened. A smart lock can provide access to a caregiver or emergency responder. Smoke and carbon monoxide detectors can connect to professional monitoring. Cameras and two-way audio can enable someone miles away to see, hear and respond.Individually, these are technologies. Together with people and services, they begin to look like infrastructure.Home-As-A-Platform For Aging And CaregivingMy MIT AgeLab colleagues, research scientists Drs. Chaiwoo Lee and Shabnam FakhrHosseini, who explore the future of the home and technology, describe the opportunity this way: “The home is more than shelter; it is a platform of people and services enabled by technology. Our vision of technology in the home is one where the home evolves with us, providing convenience in youth, connectivity in a busy middle age, and ultimately care in older age.”That evolution matters because aging-in-place may also mean aging alone. Millions of older Americans live by themselves. Women are especially likely to live alone at advanced ages; U.S. Census data show that more than four in ten women age 75 and older live alone. Living alone does not mean being lonely, frail or incapable. For many, living independently is precisely the goal.But one person living behind one front door changes the math of security.There may be no spouse who smells the smoke, notices that something is different, hears a fall, or realizes a door has been left unlocked. The person who cares most may live across town or across the country.This is where technology becomes a valuable part of longevity preparedness. High tech cannot replace high touch. A sensor isn't a daughter. A monitoring center isn't a spouse. A camera isn't a neighbor checking in.But high tech can extend the reach of high touch. And where no one else is there, it can provide another layer of awareness and response.Aging-In-Place Requires A SystemFinson shared a story from her own home. A carbon monoxide detector alerted Brinks Home's professional monitoring center while she was away. The fire department was dispatched. Using connected technologies, she could see responders arrive, communicate with them, provide access to the house remotely, and even tell them where her very large dog was hiding.No single device solved the problem. Neither did any single person. The response came from a security architecture, a system, that included technology, professional monitoring, homeowners, and first responders.That may be a useful model for thinking about security in a longer life. Security is no longer simply about keeping threats outside. It is also about detecting what is happening inside, communicating that information, and ensuring someone, or some service, can respond.Security Is Ultimately About TrustEvery new capability comes with a decision. Who can see the camera? Who gets an alert? Who knows when I leave the house? Who can unlock my door? What information does a monitoring company receive? At what point does my daughter's desire for reassurance begin to feel like surveillance?Finson describes trust as “absolutely critical” because customers are entrusting others with “the things that are the most important to you in life. Your family, your well-being and your valuables.”That is why security preparedness isn't simply about installing technology. It is about consciously designing an architecture of people, technology, and services around how we want to live.Too often those decisions are made after something happens. A fall occurs, then we buy the pendant. A parent doesn't answer one morning, then the family discusses who should have access. Someone has a scare, then a neighbor gets the key.Sometimes the decisions aren't really made at all. They happen by default. Preparedness means consciously deciding what we want, whom we trust, and how we want life to be managed when we can't manage everything ourselves.It means making choices before circumstances make them for us and recognizing that those choices will change. The architecture we want at 65 may look very different at 75 or 85. Needs change. Families change. A spouse dies. A daughter moves away. A caregiver enters the picture. Our own perception of privacy and security may change as well.Trust isn't binary. It is permissioned, contextual, and dynamic.Is Your Home Prepared? Ask 5 QuestionsSo perhaps every household needs what might be a simple home security preparedness checklist and discussion with family, friends, and service providers:What happens if something goes wrong and no one else is home?Who needs to know, and who will respond?What information am I willing to share, with whom, and under what circumstances?Could someone I trust help me from 500 miles away?When will we revisit these decisions as my needs and relationships change?The answers help determine what combination of family, friends, technology, professional monitoring, and other services belongs in our own security architecture.Finson put it well: “It's not necessarily about having to make a choice between being independent and being secure.”A longevity-ready home to age-in-place isn't simply a safer, more accessible home. It is a home surrounded by an architecture of people, technology, and services that can detect, communicate, and respond even when we, or the people who care about us, cannot.Aging-in-place is about where we live. Longevity preparedness is about consciously building what will enable us to continue living there, on our own terms.
