The entire curve shifted and grew, magnifying the impact of policy choices. At one end central banks crush growth to rein in inflation, raising recession risk and damaging equities. At the other end, central banks go easy and face the risk of inflation soaring. Bond prices fall as investors demand a higher term premium.

Generally, free radicals attack the nearest stable molecule, "stealing" its electron. When the "attacked" molecule loses its electron, it becomes a free radical itself, beginning a chain reaction. Once the process is started, it can cascade, finally resulting in the disruption of a living cell. Some free radicals arise normally during metabolism.
