After 50, things can start slipping…

You might get less exercise. Your brain is less challenged. Your social world may begin to shrink. And each of these changes tends to accelerate the others.

No single fix works on its own. Research consistently shows that combining movement, cognitive training, and social connection (and doing them regularly!) can make a real difference.

CoDo gives you and a friend or loved one a six-minute daily activity goal - walk together, train your brain together, breathe together - in compelling destinations that make you actually want to show up.

The Science

Built on rigorous research,
not wishful thinking.

CoDo's brain training is informed by the ACTIVE trial: a 20-year NIH-funded study of 2,832 adults that found speed-of-processing training associated with a 25% lower risk of dementia. That, combined with purposeful daily movement and social interaction, gives you your best shot at combatting cognitive decline.
