paragraph_text: The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole (die - ASS - toe - lee), followed by a period of robust contraction and pumping of blood, dubbed systole (SIS - toe - lee). After emptying, the heart immediately relaxes and expands to receive another influx of blood returning from the lungs and other systems of the body -- before again contracting to pump blood to the lungs and those systems. A normally performing heart must be fully expanded before it can efficiently pump again. Assuming a healthy heart and a typical rate of 70 to 75 beats per minute, each cardiac cycle, or heartbeat, takes about 0.8 second to complete the cycle.

paragraph_text: It is commonly believed that the first examples of wedding rings were found in ancient Egypt. Relics dating to 6,000 years ago, including papyrus scrolls, are evidence of the exchange of braided rings of hemp or reeds between spouses. Ancient Egypt considered the circle to be a symbol of eternity, and the ring served to signify the perpetual love of the spouses. This was also the origin of the custom of wearing the wedding ring on the ring finger of the left hand, because the ancient Egyptians believed that this finger enclosed a special vein that was connected directly to the heart, denominated in Latin the ``Vena amoris ''.

paragraph_text: However, this was not always the case; in the early 20th century, once it became apparent that the "sport" was worked, pro wrestling was looked down on as a cheap entertainment for the uneducated working class — an attitude that still exists to varying degrees today. The French theorist Roland Barthes was among the first to propose that wrestling was worthy of deeper analysis, in his essay "The World of Wrestling" from his book Mythologies, first published in 1957. Barthes argued that it should be looked at not as a scamming of the ignorant, but as spectacle; a mode of theatric performance for a willing, if bloodthirsty, audience. Wrestling is described as performed art which demands an immediate reading of the juxtaposed meanings. The logical conclusion is given least importance over the theatrical performers of the wrestlers and the referee. According to Barthes, the function of a wrestler is not to win: it is to go exactly through the motions which are expected of them and to give the audience a theatrical spectacle. This work is considered a foundation of all later study.
