You can stave off dementia by keeping your brain active. Like doing crossword puzzles.

Physically active people have less dementia. My father worked out at the downtown Rochester YMCA for two hours every single day. He began running in his 40s and routinely ran 10 miles each day til his hips gave out in his 60s. But he still continued to work out into his late 70s.
Dementia ran faster.
The brain is a complex system. So is the human body. We’d love easy answers. Definitive preventive measures.
