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.
The transaction is structured as a sale of the bond, with an agreement to repurchase it the next day at a higher price that factors in the dealer's interest expense. A dealer may also finance a customer's ownership of a bond by lending money and accepting the bond as collateral. This is a reverse repo and is structured as a purchase of the bond with an agreement to resell it to the customer the next day at a lower price that factors in the customer's interest expense.
