A Science study of more than 1,000 centenarians identified about 150 genes that predict living past 100 with 77 percent accuracy, though researchers say lifestyle matters too. The writer then recounts long-lived people who credited cod liver oil, a near-vegetarian diet or lemon juice.

Longevity Genes Help You To Live Longer, So Does Physical Activity
Tom Perls and colleagues report in Science that a model built on 150 genetic variants predicts who reaches 100 with 77 percent accuracy. The study's funder notes environment matters too, and cited research suggests highly active 65-year-olds may gain about 5.7 extra healthy years.

Genes determine your lifespan - study
A Science study compared gene variants in more than 1,000 centenarians and a similar number of controls. Tom Perls' team found 150 markers common among the very long-lived, and a statistical model built on them predicts lifespan with up to 77 percent accuracy.

Warning: This Daily Habit is Damaging Your Bones, Brain, Kidneys, and Thyroid
Chemist Paul Connett argues in The Case Against Fluoride that the chemicals used to fluoridate water are phosphate fertilizer waste, that fluoridation medicates people without dose control or federal regulation, and that evidence swallowing fluoride prevents decay is weak.

Teenage Girls are in Drug Dependency Crisis
A Partnership for a Drug Free America survey found 70% of teenage girls thought drugs and alcohol could help them cope with problems at home, while boys more often drank to loosen up socially. From 2008 to 2009 girls' alcohol use rose 11% and marijuana use 29%, against 2% and 15% for boys.

Are You Making This "Fat Storing" Mistake Before You Exercise?
Several studies suggest exercising on an empty stomach burns more fat, including one in which cyclists who trained without eating burned significantly more. Mercola notes the science is contested, with warnings about dizziness and later overeating.

One in five childbearing women childless
A Pew analysis of census data finds about 20 percent of US women of childbearing age are childless, up from 10 percent in the 1970s, while the rate among women with a master's or doctorate fell from 31 percent in 1994 to 24 percent in 2008.

This is Now Considered a Critical Piece of Cancer Treatment…
New US guidelines say cancer patients should stay physically active during and after treatment, aiming for the same 150 weekly minutes of moderate aerobic exercise recommended for everyone, with clinicians tailoring the advice to each patient.

Scientists Discover an Amazing and Simple Way to Improve Your Vision…
Mercola cites Harvard psychologist Ellen Langer's work in which people led to believe they could see especially well read more letters, including on a reversed eye chart. The researchers say visual perception rests partly on experience-based expectations; Mercola reads it as the placebo effect.

Obesity Takes Toll After 40
A study comparing medication use among normal-weight, overweight and obese Americans aged 25 to 70 found the gap widened mainly after 40. Mercola counters that counting prescriptions is a poor measure of health, since many drugs are not needed and many conditions go undiagnosed.

The Major Exercise Mistake I Made for Over 30 Years...
A study in Science Translational Medicine found metabolic changes from 10 minutes on a treadmill were still measurable an hour later, and that fitter people appeared to burn more fat. Mercola argues the study leaves out how much the type of exercise matters.

Long-Term Study Links Chronic Insomnia to Increased Risk of Death
Mercola cites research presented at SLEEP 2010 in which 2,242 people were surveyed over up to 19 years. Chronic insomnia carried roughly three times the adjusted all-cause death risk, with the highest figures for early-awakening and sleep-maintenance insomnia.

The 9 Worst Places for Your Health
Mercola passes along an MSNBC list of poor spots for health: a toothbrush beside the sink, shoes in the bedroom closet, hot leftovers put straight in the fridge, a handbag on the kitchen counter, medicine in a warm bathroom cabinet, and the middle stall in a public bathroom.

Sun Safety Tips: Beyond Sunscreens
The Environmental Working Group suggests choosing sunscreens with zinc, titanium dioxide, avobenzone or Mexoryl SX, and avoiding oxybenzone, retinyl palmitate, added insect repellent, sprays, powders and SPF above 50. It treats sunscreen as secondary to clothes, shade and sunglasses.

Which Country Makes the World’s Deadliest Cigarettes?
A study found US-made cigarettes carry more tobacco-specific nitrosamines, the major cancer-causing substance in tobacco, than brands sold in Canada, Australia and the UK, differences attributed to tobacco type, curing practices and the fertilizers used to grow it.

New Study Shows Profound Impact of Anger on Your Health…
University of Valencia researchers induced anger in 30 men using 50 first-person phrases and measured them before and after. Heart rate, arterial tension and testosterone rose, cortisol fell, and the left brain hemisphere became more active, with a more negative reported mood.

Why Walking and Aerobics Won’t Get You as Healthy as You Think
Over six months, an aerobic fitness program outperformed a pedometer-based walking program on systolic blood pressure, peak oxygen intake and ventilatory threshold, though both groups cut body mass, waist size and resting heart rate. Mercola says walking needs fast intervals to work.

Brushing teeth twice a day lowers heart disease risk?
Mercola relays a study of more than 11,000 adults linking twice-daily tooth brushing to lower heart disease risk, and notes researchers still cannot say whether poor oral health causes heart disease or simply marks it, since gum inflammation also tracks with clogged arteries.
