Perhaps U.S. Supreme Court Justice Stephen Breyer ought to confine his love of cycling to bikes of the indoor and stationary kind.

Breyer underwent "reverse shoulder replacement surgery" on April 27 at MedStar George­town University Hospital after falling from his bike the day before, near the Korean War Veterans Memorial in Washington. An exposed tree root may have been the culprit. The 74-year-old justice was released from the hospital on April 29, but not before missing that morning’s court session. He may be wearing a sling under the black robe for the next several court sessions.
