7-9 hours

The National Sleep Foundation is out with new recommendations for the amount of sleep people should get at different ages. For 18- to 25-year-olds, a new age category, the foundation’s scientific advisory council suggests getting seven to nine hours each night. [The Huffington Post]

10 percent drop

The Obama administration has pushed back the date by which it aims to end chronic homelessness by one year, to 2017. The number of chronically homeless people has dropped 10 percent since 2010. [Associated Press]

16 percent

Following a well-received speech at the Iowa Freedom Summit, Wisconsin Gov. Scott Walker gained standing among Iowa Republicans, taking 16 percent in a poll of potential Iowa caucus voters. Still, as my colleague Harry Enten explains, chaos is the true champion in the poll. [FiveThirtyEight]

34 percent

$80

Buffalo Bills head coach Rex Ryan knows how to commit to a new gig. Last Friday, the ex-Jets coach got his tattoo of his wife in a Mark Sanchez Jets jersey color-corrected to a tattoo of his wife in a Bills jersey. The incoming coach was charged $80 by a Scottsdale, Arizona, tattoo shop, which is a total bargain, because I paid at least $120 to a guy on St. Mark’s Place to tattoo the damn FiveThirtyEight fox on my neck.

$50 million

RadioShack, a vestigial organ of the American economy, is being delisted from the New York Stock Exchange.

The Shack has a market cap of $24.19 million and negative shareholders’ equity. Good night, sweet prince. [NYSE via The Wall Street Journal]
