A new study confirms earlier reports that anemia — a condition caused by having too little hemoglobin, the oxygen-carrying component of red blood cells — increases the risk for dementia. It found that having high hemoglobin levels does so as well. Dutch researchers looked at 12,305 people without dementia at the start of the study, measuring their hemoglobin levels and following them for an average of 12 years. Over the period, 1,520 developed dementia, including 1,194 with Alzheimer’s disease. The study is in Neurology. (Bakalar, 7/31)

I’ve been a runner for 25 years and have been practicing yoga for 10. So why do I find it so much less painful to run for an hour than stand for an hour? Even the thought of standing for extended periods makes my back ache, especially during the summer, where standing is part of the fabric of the season, from waiting in line at amusement parks to standing in the security checkpoint queue at the airport. “The way we stand is so important.

When standing, most people’s tendency is to assume a “relaxed” stance, with the arch of the foot collapsed and your foot rolled in slightly, she said. (Ketteler, 8/1)

We joke and call her Seabiscuit because she’s like a racehorse.” (Berg, 7/31)

When North Carolina State University microbiologist Benjamin Chapman makes a smoothie, he like many of us uses frozen berries. But first, Chapman microwaves his frozen berries to boiling and then refreezes them again before tossing them into the blender. Why the extra steps? Chapman wants to be sure that there are no pathogens in the frozen berries that could cause a foodborne illness for him or his family. (Squires, 7/31)

Kaiser Health News: The Talk Seniors Need To Have With Doctors Before Surgery

The decision seemed straightforward. Bob McHenry’s heart was failing, and doctors recommended two high-risk surgeries to restore blood flow. Without the procedures, McHenry, 82, would die. The surgeon at a Boston teaching hospital ticked off the possible complications. Karen McHenry, the patient’s daughter, remembers feeling there was no choice but to say “go ahead.” It’s a scene she’s replayed in her mind hundreds of times since, with regret. (Graham, 8/1)
