  1. Cellphones harm sperm quality

    Cellphones can harm male fertility

    Men, if you're hoping to have kids -- either for the first time, or just want to add to your brood -- then do yourself a favor and take that cellphone out of your pocket.

    Despite what you've heard, the radiation from cellphone exposure is neither harmless nor negligible -- and when it's in your pocket, it can wipe out your hopes for future generations.

    One new review of 10 studies finds that keeping a phone in your pocket can lead to slower sperm that can't find the egg.

    In men with no cellphone exposure, between 50 percent and 85 percent of sperm have that natural ability to move toward the egg, called motility. But if you keep a cellphone in your pocket, that number drops by about 8 percent.

    Even worse, the review finds that it can also lead to a similar reduction in the number of living sperm.

    Sperm are very sensitive to radiation, especially the electromagnetic radiation emitted by cellphones.

    It's not too dissimilar from the type of radiation used in microwave ovens, so it's probably not entirely inaccurate to say that your cellphone could be cooking your sperm to death.

    That's why, for example, a 2006 study found that men who used cellphones had measurably lower sperm counts than men who didn't. And remember, the phones of 2006 were very different -- they were smaller, more limited in function and we used them less.

    It's quite possible that today's phones, which have bigger batteries and more powerful antennas to handle more functions, could do even more damage.

    On the other hand, what your phone does to your testicles is nothing compared to what it'll do to your brain -- because emerging evidence confirms that regular cellphone use can increase the risk of brain tumors.

  2. Walking can ease peripheral artery disease

    Take a step away from PAD

    If you're on the other side of 50, you almost certainly know someone with peripheral artery disease. You might even have it yourself, because it's one of the most common conditions among older Americans.

    PAD, as it's called, is when some of your arteries start to narrow, usually in the legs. It can lead to pain and difficulty walking, which is bad enough. But even worse, it can also increase your risk of heart attack and stroke.

    If your doctor spots it, he'll almost certainly recommend a stent to prop those arteries back open.

    But new research confirms what I've been telling my own patients: A stent should be your absolute last resort, because you can reverse PAD entirely on your own, without drugs or surgery.

    And all you need to do is walk a little more.

    Walk five days a week for about 50 minutes a day, and you can expect both your speed and distance to improve. In the new study, PAD patients who stuck to the program -- entirely on their own -- were able to walk 87 feet further during a six-minute test one year later.

    PAD patients who didn't walk, on the other hand, actually lost 25 feet during that test.

    This isn't just a race to see who can go further or faster. Distance and speed are key markers of the progression of PAD. If you can pick up the pace a little, the condition is likely improving.

    And if you can't, you're a prime candidate for that stent.

    If walking a little more can help you avoid that, then lace up your shoes and get moving -- it's worth the effort, because once that stent is in, you'll be expected to live with it for the rest of your life.

    And whatever you do, don't assume that pain and difficulty walking are normal parts of aging.

    They're not -- they're warning signs of something wrong, including PAD, and if you're having trouble getting around yourself, don't wait for it to get worse.
