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.

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.
While the mechanics of a repo involve buying and then reselling securities at a set price and a set time, at its financial essence, a repo is a collateralized loan. Fed repos can be conducted for terms anywhere from one to 65 business days. They are usually overnight, though rarely longer than 14 days.
