As Boomers start to live longer, finding ways to improve brain power becomes more important. There are plenty of other ways to improve brain power. The main idea is to constantly try new things and seek out the unfamiliar in an attempt to get the brain really working on figuring things out. Take day trips and see something new.
For instance, go to an art museum. Gazing at artwork which is open to interpretation forces the brain to come up with some sort of explanation for what it is seeing. Since most art tells some sort of story, there are always plenty of good brain teasers at places like this. Just keep your mind working and active. That’s the most important thing.
