And I should say he's in his 60s.

Brain HQ is part of a company called Posit Science that has really taken a much more academic approach to mental fitness than most of the other companies out there.

There are now well over 100 academic studies that have used the Brain HQ exercises.

They looked at people who had all kinds of different conditions like ADHD, early dementia, traumatic brain injuries, and just normal aging.

A couple of months ago, brain HQ exercises were part of this huge study done by the Alzheimer's Association.

Not exactly.

OK.

The study was looking at whether this combination of lifestyle changes, you know, including mental exercise, could slow down the cognitive declines you usually see in people in their 60s and 70s.

OK.

So there were more than 2,000 people in this study.

It went on for two years.

It cost them about $50 million to do.

The others were given a very specific diet.
