1. Hearing loss linked to cognitive decline

    Lose your hearing, lose your head

    As a doctor, I'm an expert at delivering bad news. So I'm here today to perform an intervention on behalf of every poor sap who has to deal with you during the course of a day.

    Be honest with yourself, friend. Each Sunday you move closer to the front of the church, and it's not because you're getting more religious. The postman may always ring twice, but he has to ring five times before YOU realize somebody's at the door. You have Wheel of Fortune turned up so loud, Pat Sajak is practically screaming vowels.

    YOU'RE DEAF AS A POST, and it's high time you did something about it. Because by leaving your hearing loss untreated, you're not just missing out on all the wonderful conversations life has to offer -- you're actually getting dumber, one day at a time.

    Can you hear me now?

    A new study from Johns Hopkins found that once you develop hearing loss, your brain starts shrinking at warp speed. Researchers followed 126 seniors and found that folks with hearing loss were more likely to be cruising down the pothole-pocked road to senility. And this isn't the first study to link bad ears with a rotting brain -- it's just the latest.

    I'm older than Methuselah's uncle, but I could hear a ladybug peeing on cotton. I've always taken my hearing seriously, which is one way I'm keeping my brain bigger than a breadbox.

    Stop treating hearing loss as a rite of passage. Swallow your pride and get those bum ears checked out today. Because between good hearing and reading my Daily Dose every day, there's going to be no stopping that super brain of yours.

  2. Fats boost brain power

    Omega-3s shown to be brain boosters

    Fish is brain food -- and this isn't just something mom cooked up to make you eat your tuna. Science has backed her up so many times you'd have to be missing gray matter yourself to argue with her on this one.

    The secret is in the fats -- because the same omega-3s found in fatty fish are also found in your brain.

    And your brain needs more to keep sharp.

    If you've been missing out, it's not too late. You can get your own thinking cap back in working order by adding a fish oil supplement -- and you can start to see a real difference in as little as five weeks.

    That's how long the latest study lasted -- five weeks. And in that time, 40 people between the ages of 51 and 70 were given either 1500 mg EPA and 1,100 mg of DHA, or a placebo, each day.

    Do I even need to tell you what happened next?

    The folks who got their fish oil got big-time benefits in the noggin -- including a boost in cognitive scores, especially in the all-important area of working memory.

    But this isn't exactly new. Like I said, it's been proven time and again. One study earlier this year even found that seniors with high levels of DHA had the most brain volume.

    That means they had the most brain -- and yes, more is better when it comes to your noggin, especially in your senior years. That's when all our brains shrink a little, but brains that shrink faster are usually the ones that stop working sooner.

    And that's when senility, dementia, and Alzheimer's kick in.

    By the way, the patients in the new study didn't just see improvements in working memory. They also had better fasting glucose levels and lower levels of a key marker for inflammation -- and the ones who had the biggest improvements in glucose and inflammation also had the best cognitive scores.

    This isn't unexpected, since fish oil is one of nature's most powerful inflammation fighters -- and another new study confirms it.
