Terence Newman, the oldest cornerback in the NFL at 37, has revealed one of the secrets to his longevity.

“Red wine is the key,” the Vikings’ starter said Tuesday. “Get it in your veins, baby. Keeps you strong.”

Newman celebrated his most recent birthday last Friday. On Tuesday, he showed up at practice wearing the No. 23 he had with Cincinnati the previous three seasons.

Newman switched from No. 30 following the availability of No. 23 when running back Joe Banyard was waived last week. Newman said he “just did it” and he doesn’t consider the number anything special.

What might be special, though, is advice he has given Minnesota’s defensive backs about how to play to an advanced age. It includes that certain beverage.

“He’s got something special going on, so we’re all trying to get his secrets,” said safety Harrison Smith. “That was the one that he gave us was a little bit of red wine every now and then. We’ll see how it goes. It’s got to be red. It’s good for your heart, I guess.”
