MIT AgeLab reveals 8 keys to preparing for longevity

Most people plan for retirement, but almost nobody prepares for it. That distinction, drawn by Dr. Joseph Coughlin, founder of the MIT AgeLab, anchors a conversation on the Mel Robbins Podcast about what it actually takes to age well. Planning is the intent, like writing a grocery list. Preparedness is whether the food actually makes it into the cart, the cabinet, and onto the plate.

Why retirement is a third of adult life

Coughlin breaks adult life into rough 8,000 day blocks: birth to 21, 21 to the mid-40s, mid-40s to 65, and 65 to the mid-80s. Framed that way, retirement stops looking like a short bonus round of grandkids and beach walks and becomes a full third of adult life, roughly the same length as early adulthood itself. A child born today has roughly even odds of living to 100, which means the years after 65 deserve as much intentional planning as the decades that came before them.

Three questions that expose the real gaps

Rather than asking what someone wants to do in retirement, Coughlin asks three smaller, more revealing questions. First, do you know how you would get an ice cream cone on a whim, given that 70 percent of Americans over 50 live somewhere they cannot get around without driving. Second, what will you actually do on an ordinary Tuesday at 10:30 in the morning, a time slot research shows the average couple over 65 fills with four to five hours of daily television once the structure of work disappears. Third, who is going to change your light bulbs, meaning who do you trust enough to handle both the physical tasks and the decisions once you or a loved one no longer can.

The suit that simulates being 90

To make aging tangible rather than abstract, the AgeLab built Agnes, the Age Gain Now Empathy System: a weighted, restrictive suit with fogged goggles, a neck brace, and stiffened gloves that simulates reduced muscle mass, joint stiffness, impaired vision, and diminished grip strength. Wearing it turns ordinary tasks, picking up a laundry basket, texting a photo, standing up from a low chair, into visibly exhausting effort. The exercise is designed to produce a specific kind of empathy: understanding that a parent or grandparent moving slowly isn't being difficult, they are managing friction, fatigue, and frustration that isn't visible from the outside.

Loneliness carries a measurable health cost

Social connection turns out to matter as much as physical health. Research cited in the conversation found that loneliness and social isolation carry a health impact comparable to smoking 11 to 15 cigarettes a day. Coughlin describes friendship in old age as a portfolio that needs active management, since friend groups naturally shrink through death, relocation, and even the arrival of grandchildren, which quietly displaces the social time couples used to spend with peers.

Eight dimensions of a longevity preparedness index

Working with insurer John Hancock, the AgeLab built an index covering eight dimensions: health, finances, community, home, life transitions, daily activities, social connection, and caregiving. Community turned out to be more predictive than most people expect. Zip codes just a few miles apart can carry a 9 to 13 year difference in life expectancy, largely driven by intensity, density, and accessibility of the things people need. Caregiving scored the lowest of all eight, with only 42 out of 100.

The caregiving gap almost nobody discusses

Seventy percent of people assume a spouse or adult child will provide their care, but only 30 percent have actually had that conversation. In practice, caregiving falls disproportionately on the oldest adult daughter, and it carries a physical, emotional, and financial toll: caregivers report more fatigue and depression, and many step back from promotions or leave jobs entirely, which compounds financial risk for a group already likely to outlive a partner by seven to eight years. Coughlin frames the fix as a recurring conversation about four questions: who will provide care, where will that care happen, what matters most (dignity, independence, comfort), and how will it be paid for.

The driving conversation nobody wants to have

One of the hardest preparedness conversations is about driving. Coughlin pushes back on the common approach of noticing at a single holiday dinner that a parent seems older and deciding on the spot that they should stop driving. Birthdays don't cause accidents, he notes, health conditions and medication combinations do, and the better approach is watching for patterns, like repeated near misses, rather than reacting to a single moment. Introducing ride share options like Lyft or Uber before they are strictly necessary lets someone build comfort with alternatives while they still have a choice, rather than facing the loss of a car and independence at the same time.

Three takeaways to start with

Coughlin closes with three concrete moves: start the caregiving conversation before a crisis forces it, build actual structure into the hours a job or caregiving used to fill, and stop postponing decisions that are easier to make now than during an emergency. None of it requires special equipment. It requires attention now, before the version of aging shown by the simulation suit becomes the reality.
