Sleeping on the left also allows much of the intestines to hang away from the very thin-walled inferior vena cava (IVC) which brings venous blood back toward the heart. Interestingly, the IVC lies against the right side of the spine, so when you lie on the left much of the viscera falls away from the IVC.
What is a 'Repurchase Agreement - Repo'. A repurchase agreement (repo) is a form of short-term borrowing for dealers in government securities. The dealer sells the government securities to investors, usually on an overnight basis, and buys them back the following day.
Repos are used also by the central banks as instruments of monetary policy. To temporarily expand the money supply, a central bank decreases the discount rate (called repo rate) at which it buys back government securities from the commercial banks, to contract or maintain the money supply it increases the repo rate. See also open repo and reverse repo.
