3. This viral tweet made a real difference.

A college student's viral tweet helped raised tens of thousands of dollars for St. Jude's Children's Hospital after being featured by Jimmy Fallon, Ellen Degeneres, and more. "This time of year is about giving—this year, I am giving back to St. Jude and the families who are supported by their amazing services," the student tweeted, vowing to donate 25 cents for every like and 50 cents for every retweet. After these numbers added up to hundreds of thousands of dollars, she started a GoFundMe to cover the funds she didn't have. It's a great reminder of easy ways to give back during the holidays.

5. Is long-distance running bad for the heart?

As it turns out, probably not. A new study on 50 men who ran 3,510 marathons collectively found that there was little relationship between how much they ran and how much plaque they had in their arteries. But the cardiac demands of years of hard running hadn't harmed their hearts either. (NYT)
