Why Exercise Boosts Brainpower

aditi sends us a report from Reuters on research indicating that exercise boosts brainpower by building new brain cells in a brain region linked with memory and memory loss. Quoting: "Tests on mice showed they grew new brain cells in a brain region called the dentate gyrus, a part of the hippocampus that is known to be affected in the age-related memory decline that begins around age 30 for most humans. Researchers used magnetic resonance imaging scans to help document the process in mice — and then used MRIs to look at the brains of people before and after exercise. They found the same patterns, which suggests that people also grow new brain cells when they exercise."

    The really sad thing is you only need 30 mins of exercise a day and cut back on junk food to lose weight, be healthy, etc. The amount of excuses I hear is pathetic. Walk, bike, lift, get into a sport, etc. Problem is so many people think the virtual world is a better place to be.

    Why are so many "body builder" types so dumb then?

    They're not "dumb", but they're also not necessarily the intellectual type. From what I've seen, the reason for that is that your intellectual spends too much time in an introverted state to worry about the world around them. Regular exercise is not engaging to their internal senses, so they tend to find it "boring". The more extroverted types get their engagement from the world around them, and thus find pleasure in physical activity.

  8. Stallone isn't dumb by gatorflux · · Score: 5, Informative

    Stallone is an accomplished script writer and a damned good businessman. Take a look at the deal he struck when he wrote and sold Rocky to the studio (he basically retained the rights to future sequels). Stallone has been able to fly under the radar because he sounds uneducated when he talks (due to an injury sustained at birth, if I remember correctly).

    There aren't any nobel prize winning boxers because they are devoting their time to boxing and not to science. I'd suspect you could find some nobel prize winners that work out.

    Actually, I remember reading about a study that indicated genius level processing in peak performing athletes. For example, an NFL quarterback can identify 3 - 5 potential receivers, track their viability, and decide how to execute a play in under a second--while avoiding defenders.

    I would argue that such ability takes a level of intelligence that, if applied to other pursuits, would be widely recognized as remarkable.
