  • My New Diabetes Articles for HealthCentral:

    Last month HealthCentral published four more of my diabetes articles about all aspects of the condition:

    Now we know how omega 3 fatty acids can help us prevent one of the most serious complications of diabetes. Fish oil from fatty fish like salmon and sardines are the best dietary source of omega 3, and one of these fatty acids, DHA, is what does it.

    Should we use the first or second drop of blood when we check our blood glucose? Can we squeeze our finger? How important is it to wash our hands first? A new study finally answers these basic questions.

    Too many people with diabetes stop checking their blood glucose because they don't think they can do anything if their level is too high. Here's what we can do.

    Some people succeed in losing weight on a structured program. Others do best on their own. It depends on what type of person you are. Where do you fit?

  • Fitness and Photograph for Fun:
  • Last month I published eight more of my articles on staying fit by getting the activity we need. Photography is what does it for me:

    Walking New York City
    New Yorkers are walkers. I joined the crowd when I went there on business in early March.

    Panama's Metropolitan National Park
    My trip to Panama started with a four-hour hike through Metropolitan Natural Park in Panama City. I experienced the country for two weeks on a Nature Conservancy birding tour.

    Panama's Canopy Lodge
    Canopy Lodge is the sister eco-lodge to the famous Canopy Tower. By staying in both during my trip to Panama I was able to experience bird life in both the highlands and lowlands of the country.

    Panama's Canopy Lodge: Bird Life
    Of all the birds that I saw around Canopy Lodge the one I appreciate the most is the Lineated Woodpecker. It looks so scared!

    Panama's Canopy Tower
    One of the world's best birding places, this former U.S. Air Force radar tower offers an unobstructed 360° view of the rainforest within Soberanía National Park.

    Panama's Canopy Tower: Bird Life
    Of all the rare and colorful birds that I saw in Panama the one that I appreciated the most was the gaudy Keel-Billed Toucan.

    Panama's Canopy Tower: Animal Life
    Monkeys were plentiful around Canopy Tower.

    Leaving Panama
    My visit to Panama was no vacation. What made the trip especially rough for me was the fall that I took and the infection that I contracted. My fall and my illness combined with the general conditions of photography in the tropical rainforest made for a rough trip. But certainly one that was worthwhile and one that I would do again even knowing what I know now. Yet iIn many ways Panama was an easy trip. I got lots of good photos, exercise, and wonderful memories. In Panama I continued to enjoy good luck.
