    > Brains. After you reach adulthood, neurons don’t divide. If some of your neurons die—which happens every day—then they’re gone. If you get a brain injury, the other neurons will try to “learn around” the injury, but the neurons themselves are never replaced.

    This is a very outdated view. Neuroscience has shown that neurogenesis continues throughout the entire life span of humans, albeit at a much slower rate. You might have a hard time recovering from a serious brain injury or stroke but losing a few brain cells won’t change a thing.
