86-year-old Hilda Knott has been playing games for the better part of 40 years and claims that they are part of the reason she's remained as sharp as she is. That's not even the most interesting part. We all know that playing games improves all of the cognitive, puzzle-solving, and memory centers of the brain.
What we didn't know was that staging drive-bys also counts as mental calisthenics. Hilda here loves her some GTA IV. Don't take this the wrong way Hilda, but do you wanna party?
