What if living past 85 with the brainpower of a 50-year-old wasn't a fluke, but something you could work toward? Meet the "Super-Agers”, a group of extraordinary older adults whose memory, vitality, and cognitive sharpness defy conventional aging. These aren’t people avoiding aging, they're redefining it.
So, what’s their secret? As it turns out, science has some pretty convincing answers.
- Their Brains Look… Younger
Researchers at Northwestern University’s Super-Aging Study found that Super-Agers have a thicker cortex, especially in areas tied to memory and attention, compared to their peers. Some of them even have brain tissue that rivals much younger adults.
Why it matters: This thickness isn’t just about brain volume. It reflects resilience to aging, helping Super-Agers stay mentally sharp.

- They Eat for Brain Power
The MIND diet (a hybrid of the Mediterranean and DASH diets) is one of the few diets scientifically proven to slow cognitive decline. It emphasizes:
- Leafy greens
- Berries
- Whole grains
- Nuts
- Fish
- Olive oil
People who stick closely to the MIND diet can reduce their risk of Alzheimer’s disease by up to 53%.

- They Have Purpose—And It Protects Their Brain
One common trait among Super-Agers? They tend to have a strong sense of purpose. Whether it’s volunteering, mentoring, or pursuing creative passions, this drive does more than just feel good, it literally protects their brains.
In a long-term study, seniors with a strong sense of life purpose had a 2.4x lower risk of developing Alzheimer’s.

- They Protect Their Sleep Like a Superpower
Sleep isn’t just rest—it’s maintenance. Groundbreaking research found that during deep sleep, the brain flushes out waste proteins that are linked to Alzheimer’s and other neurological disorders.
If you’re skimping on sleep, you’re skipping out on your brain’s nightly detox.

- They Don’t Age Alone
The longest-running happiness and health study—Harvard’s 85+ year Study of Adult Development—found that the quality of your relationships is the single biggest predictor of long life and mental health.
Strong social connections reduce chronic illness, depression, and even memory loss.

- They Move—A Lot
You don’t need to run marathons, but you do need to stay physically active. A massive meta-analysis has shown that better cardiorespiratory fitness is directly linked to a lower risk of early death and disease.
Walking, swimming, dancing, whatever gets you moving, counts.

Can You Become a Super-Ager?
The answer is: probably. While genetics plays a role, lifestyle is the game-changer. Super-Aging isn’t about perfection. It’s about consistency in key areas: mental challenge, movement, nutrition, purpose, sleep, and connection.
Aging is inevitable, but how you age is, to a large extent, up to you.
