Producing one T-shirt takes 2,700 liters of water = enough for one man to drink for 900 days

How Your T-Shirt Can Make a Difference - National Geographic: Did you know that the t-shirt on your back has a major impact on the planet? Producing it took 2,700 liters of water, plus it takes a lot of energy to get it from the cotton fields to your closet. But some of your t-shirt's biggest impacts are in how you care for it. Here's how you can help reduce its effect on the environment.

Should Doctors ‘Prescribe’ a Drink a Day? No.

From the NYTimes:

The evidence regarding wine versus other beverages like grape juice is mixed.

For most people, low-risk drinking is not harmful to health — and may be helpful. However, I would discourage people from drinking in order to improve their health.

Compared with non-drinkers, men who consumed wine, beer, or spirits had a 36% lower risk of all-cause mortality and a 34% lower risk of cardiovascular mortality.

Before you recommend wine for cardiovascular risk reduction, consider this:

- One in five men at risk of drinking problem during their lifetimes

- Women have an 8 to 10 percent chance of becoming dependent on alcohol during their lifetimes

- Men have 15% lifetime risk for alcohol abuse, 10% risk for alcohol dependence. Each cuts your life short by 10-15 years.

- Heavy drinking increases risk of depression by 40%, and 80% of people dependent on alcohol are smokers

A glass of wine daily may prolong life. How can you predict which patient will have a bottle daily though?

Tibor Banyai ‏ @tibor75: Do u tell your AF pts to be 100% abstinent? Curious RT @drjohnm: RT @DrVes: Should Doctors ‘Prescribe’ a Drink a Day? No.

John Mandrola, MD ‏ @drjohnm:  No I don't rec abstinence but I don't feel that alcohol adds to health. Mild intake prob neutral. Worry about cancer risk

People who "drink heavily every so often" are 45% more likely to develop coronary heart disease

Occasional heavy drinking was defined as having 5 or more standard drinks in a day at least 12 times per year. "Regular" heavy drinkers - those who averaged at least 5 drinks per day, were excluded from the analysis.

In general, moderate drinking - a drink or two per day - is considered a potentially heart-healthy habit. A number of studies have found that moderate drinkers have lower risks of heart disease than teetotalers do.

Research suggests that alcohol can increase "good" HDL cholesterol, has anti-inflammatory effects in the blood vessels and may make the blood less prone to clotting.

On the other hand, regular heavy drinking may increase blood pressure, promote blood clotting and contribute to development of arrhythmias.
