You can take fish oil supplements or eat lots of turmeric. You can invest in a language class, puzzle books, or a few hours of exercise every week. There are countless methods to (allegedly) improve your memory and cognitive functioning—the brain training and -assessment industry is expected to reach $8 billion by 2022, according to a major market research report.
