An interest rate equals interest earned or charged per year divided by the principal amount, and expressed as a percentage. In the simplest example, a 5% interest rate means that it will cost $5 to borrow $100 for a year, or a person will earn $5 for keeping $100 in a savings account for a year.A legal document that is a promise to repay borrowed principal along with interest on a specified schedule or certain date (the bond's maturity).hat HH bonds earn.

(July 2015) Myoclonus is a brief, involuntary twitching of a muscle or a group of muscles. It describes a medical sign and, generally, is not a diagnosis of a disease. These myoclonic twitches, jerks, or seizures are usually caused by sudden muscle contractions (positive myoclonus) or brief lapses of contraction (negative myoclonus).
Why your body jerks before you fall asleep. If you have ever wondered why peopleâs arms and legs twitch suddenly as they are drifting off to sleep, our resident psychologist Tom Stafford has the answer. As we give up our bodies to sleep, sudden twitches escape our brains, causing our arms and legs to jerk. Some people are startled by them, others are embarrassed. Me, I am fascinated by these twitches, known as hypnic jerks. Nobody knows for sure what causes them, but to me they represent the side effects of a hidden battle for control in the brain that happens each night on the cusp between wakefulness and dreams. Normally we are paralysed while we sleep.
