10 years

Harry Windsor, a well-known Briton, is leaving the armed forces after 10 years of service. Prince Harry, an Apache helicopter pilot who served 2 tours in Afghanistan, will complete his service in June. [The Guardian]


11 feet

Like lots of ice on Earth, the Totten Glacier in Antarctica is melting. This is not great; the Totten Glacier holds back a lot of ice that could otherwise go into the oceans. If that happens, sea levels could rise by 11 feet. I feel like someone should look into this. [Washington Post]

$837,000 office pool

A NFL “survivor” pool of epic proportions led the police to raid a New Jersey man’s home. The pool, run by John Bovery, was worth $837,000 in 2009, Bovery said. It had nearly 4,000 participants. [NJ.com]

16.4 million uninsured
