"It is important to know your blood type," E.R. physician Dr. Travis Stork says. "Particularly if you're pregnant. But also, it is helpful if you're ever in a trauma. We will type and screen you if you need a blood transfusion, but it's always helpful to know your blood type.
"Also, we have to encourage everyone out there to donate blood if you can," Dr. Travis adds. "You never know when your blood may save someone else's life, or God forbid, if you may need blood yourself."

• Cabernet: Highest levels of polyphenols, the heart-healthy chemical, and most flavonoids of all reds.
• Syrah/Shiraz: High in polyphenols. Australian and Californian Shiraz tend to have higher alcohol contents.
• Zinfandel: Most calories, least flavonoids and tends to have the highest alcohol content of all the reds.
• Pinot Noir: Highest resveratrol, which can help heart health, high in flavonoids and low in calories. A great choice!

When enjoying wine, women should limit themselves to one drink per day, while men should not exceed two drinks daily. Make sure to always drink responsibly and in moderation.
