The opening photo in Half, Julia Kozerski’s series of naked self-portraits, is actually the bookend to a sequence of earlier photos. In those, she appeared unhappily in her wedding dress in a changing room cubicle, more than 300lb (21 stone) and mortified. Here, she appears in the dress again, standing sideways on to the camera, to show how much of the dress is unoccupied. Over the course of a year, Kozerski lost half her body weight, and you might expect the resulting photos to conform to the glib narrative of before and after. Instead, the 28-year-old took pains to show “what real is, what raw is” – in this case stretchmarks, skin folds, contours like sand dunes. Raw is Kozerski naked, and frequently crying.

Nudity is an overused gesture in photography, particularly when it purports to “celebrate” the “ordinary”. You can’t turn on the TV (Lena Dunham), go to a gallery (Spencer Tunick) or, if you’re in San Francisco, enter a civic building these days without tripping over someone getting their kit off in the name of corporeal democracy. That Kozerski still manages to be shocking and interesting is testament to her ideas and her courage. The question most people ask on seeing the photos – after “Why don’t you get surgery to remove the extra skin?” – is “How did you get the weight off?” which she thinks misses the point. Losing the weight was tough, she says: “I had no idea who I was, and while I went through all that I was lost.” But what came after was tougher. Contrary to media everywhere, being thin isn’t enough of an identity to go on. “This is it!” she thought, when she finally got her weight down, and then: “Now what do I do?”

Exercise ‘keeps the mind sharp’ in over-50s, study finds – BBC News

Doing moderate exercise several times a week is the best way to keep the mind sharp if you’re over 50, research suggests.
Thinking and memory skills were most improved when people exercised the heart and muscles on a regular basis, a review of 39 studies found.
This remained true in those who already showed signs of cognitive decline.
Taking up exercise at any age was worthwhile for the mind and body, the Australian researchers said.
Exercises such as T’ai Chi were recommended for people over the age of 50 who couldn’t manage other more challenging forms of exercise, the study in the British Journal of Sports Medicine said.

A neuroscientist says there’s a powerful benefit to exercise that is rarely discussed

The immediate effects of exercise on my mood and thought process proved to be a powerful motivational tool. And as a neuroscientist and workout devotee, I’ve come to believe that these neurological benefits could have profound implications for how we live, learn and age as a society.

Let’s start with one of the most practical immediate benefits of breaking a sweat: exercise combats stress. Exercise is a powerful way to combat feelings of stress because it causes immediate increases in levels of key neurotransmitters, including serotonin, noradrenalin, dopamine and endorphins, that are often depleted by anxiety and depression. That’s why going for a run or spending 30 minutes on the elliptical can boost our moods immediately—combatting the negative feelings we often associate with chronic stressors we deal with every day.

Scientists tested 30 Apple iPhone fitness apps

If browsing the Apple App Store for a fitness app and going through the hundreds of choices is enough to make your brain explode, check out this new study from the University of Florida.

Researchers rounded up 30 popular free fitness apps for the iPhone, dissected what they do, and compared this against American College of Sports Medicine guidelines for physical activity.

In scoring the apps, researchers looked at everything from warm-ups, cool-downs and stretching to safety and assigned them a score for three separate categories: aerobic exercise, strength/resistance and flexibility.
