Women’s breasts age faster than the rest of their body: Different parts of the body appear to age at different rates, according to “a new system that may be the most accurate way yet of identifying a person’s age from a blood or tissue sample.” Perhaps due to hormone exposure, women’s breasts appear to be about two to three years older than the woman’s chronological age, while “heart tissue appeared nine years younger than true age.” Interestingly, “cancerous tissue also appeared to age prematurely, coming out at 36 years older than the person’s actual age on average across 20 cancers from 20 different organs.” 

Surgery trounces diet and exercise for treating obesity and its ills: While there’s no question that diet and exercise are an effective way to slim down, a new study suggests that “procedures such as gastric bypass, sleeve gastrectomy and gastric banding beat diet and exercise. By a long shot.” The study, published in the British Medical Journal, followed people after surgery for six months to two years. Researchers found that people who “got weight-loss surgery lost on average 57 more pounds than those in nonsurgical weight programs.” Type 2 diabetics who got surgery were also 22 times more likely to see their diabetes resolve, and those with metabolic syndrome were 2.5 times as likely to improve after surgery.
