Men are Responsible for More Car Accidents Compared to Women

Men are Responsible for More Car Accidents Compared to Women Get the men out of the roads and we will have fewer and less fatal accidents. Since time immemorial, men took risks with their lives and lived much less carefully compared to women.

The expression of this tendency on the roads is in the higher instances of drunk driving, generally riskier driving habits, and fast driving. The role of men in car accidents supersedes that of women. Men are responsible for causing a larger number of fatal car accidents compared to women. Drunk driving is one of the most common causes of road accidents. As a laxative, alcohol interferes with coordination of the body. This makes it relatively more difficult to control a vehicle on the road. Drunk drivers cannot respond quickly enough to emergencies because of the reduced coordination of the senses. In some cases, a driver may actually fall asleep behind the wheel under the influence of alcohol. Statistically speaking, men are more likely to drink and drive compared to women. Shefer notes that, â€Å"men constitute the majority of drug abusers and are greater consumers of alcohol than women† (25). In situations where women drink and drive, they take lesser alcohol compared to men. These makes men responsible for more of the drink and drive related accidents, and generally increases the instances of accidents caused by men. From a risk perspective, men have a higher tendency to take risks compared to women. Arguably, risk is part of the male psyche. They tend participate to risky activities more than women. Some psychologists suggest that the risk impulse in men results from higher levels of the hormone testosterone. This partly explains why more men than women participate in high adrenaline sports such as bungee jumping, deep-sea d iving and sky diving. Nature conspired to provide men with a higher risk affinity compared to women thereby predisposing them to risky living habits. Advertising Looking for essay on gender studies?

Men will overtake around blind corners, they will drive closer to other vehicles, and they will try to beat the train at the railway crossing, all this for the kick of it! Bartley reports that in Brazil, road accidents kill 30,000 people annually, with men accounting for 82 percent of the fatalities (226). This clearly demonstrates the results of some of the risky male habits on the roads. Over speeding is a well-known cause of road accidents. Men tend to drive faster than women do. This explains why there are more male drivers in racing sports compared to women. It is easier to find a group of young men racing their cars in the free way or in the suburban compared to finding young women of the same age doing the same. In mixed-sex races, men tend to dominate the motor sports. The expression of the male desire to speed on the roads shows when more men drive faster than recommended speed limits, increasing the likelihood of high speed accidents. When discussing car accidents, Dorn states among other thing that the safety of a car depends on â€Å"their effective use† (136). It presupposes recommended driving speeds under given the environmental conditions, which men ignore, ending up in fatalities. The way to safer roads, it seems, is to reduce the number of men in our roads. Bartley, Graham. Traffic accidents: causes and outcomes. New York: Nova Science Publishers, 2008. Print. Dorn, Lisa.

Dromedary Camel (Camelus dromedarius)

Dromedary Camel (Camelus dromedarius) The dromedary (Camelus dromedarius or one-humped camel) is one of a half-dozen of camel species left on the planet, including llamas, alpacas, vicunas, and guanacos in South America, as well as its cousin, the two-humped Bactrian camel. All evolved from a common ancestor some 40-45 million years ago in North America. The dromedary was probably domesticated from wild ancestors roaming in the Arabian peninsula. Scholars believe that the likely site of domestication was in coastal settlements along the southern Arabian peninsula somewhere between 3000 and 2500 BC. Like its cousin the Bactrian camel, the dromedary carries energy in the form of fat in its hump and abdomen and can survive on little or no water or food for quite a long period. As such, the dromedary was (and is) prized for its ability to endure treks across the arid deserts of the Middle East and Africa. Camel transport greatly enhanced overland trade throughout Arabia particularly during the Iron Age, extending international contacts throughout the region along caravansaries. Art and Incense Dromedaries are illustrated as being hunted in New Kingdom Egyptian art during the Bronze Age (12th century BC), and by the Late Bronze Age, they were fairly ubiquitous across Arabia. Herds are attested from Iron Age Tell Abraq on the Persian Gulf. The dromedary is associated with the emergence of the incense route, along the western edge of the Arabian peninsula; and the ease of camel travel compared to substantially more dangerous sea navigation increased the use of overland trade routes connecting the Sabaean and later trading establishments between Axum and the Swahili Coast and the rest of the world. Archaeological Sites Archaeological evidence for early dromedary use includes the predynastic site of Qasr Ibrim, in Egypt, where camel dung was identified about 900 BC, and because of its location interpreted as dromedary. Dromedaries did not become ubiquitous in the Nile Valley until about 1,000 years later. The earliest reference to dromedaries in Arabia is the Sihi mandible, a camelid bone direct-dated to ca 7100-7200 BC. Sihi is a Neolithic coastal site in Yemen, and the bone is probably a wild dromedary: it is about 4,000 years earlier than the site itself. See Grigson and others (1989) for additional information about Sihi. Dromedaries have been identified at sites in southeastern Arabia beginning between 5000-6000 years ago. The site of Mleiha in Syria includes a camel graveyard, dated between 300 BC and 200 AD. Finally, dromedaries from the Horn of Africa were found at the Ethiopian site of Laga Oda, dated 1300-1600 AD. The bactrian camel (Camelus bactrianus or two-humped camel) is related to, but, as it turns out, not descended from the wild bactrian camel (C. bactrianus ferus), the only survivor species of the ancient old world camel. Domestication and Habitats Archaeological evidence indicates that the bactrian camel was domesticated in Mongolia and China about 5,000-6,000 years ago, from a now-extinct form of camel. By the 3rd millennium BC, the bactrian camel was spread throughout much of Central Asia. Evidence for the domestication of Bactrian camels has been found as early as 2600 BC at Shahr-i Sokhta (also known as the Burnt City), Iran. Wild bactrians have small, pyramid-shaped humps, thinner legs and a smaller and slender body then their domestic counterparts. A recent genome study of wild and domestic forms (Jirimutu and colleagues) suggested that one characteristic selected for during the domestication process may have been enriched olfactory receptors, the molecules which are responsible for the detection of odors. The original habitat of the bactrian camel extended from the Yellow River in Gansu province of northwest China through Mongolia to central Kazakhstan. Its cousin the wild form lives in northwestern China and southwestern Mongolia particularly in the Outer Altai Gobi Desert. Today, bactrians are mainly herded in the cold deserts of Mongolia and China, where they contribute significantly to the local camel herding economy. Attractive Characteristics Camel characteristics which attracted people to domesticate them are pretty obvious. Camels are biologically adapted to harsh conditions of deserts and semi-deserts, and thus they make it possible for people to travel through or even live in those deserts, despite the aridity and lack of grazing. Daniel Potts (University of Sydney) once called the bactrian the principal means of locomotion for the Silk Road bridge between the old world cultures of the east and west. Bactrians store energy as fat in their humps and abdomens, which enables them to survive for long periods without food or water. In a single day, a camels body temperature can vary safely between an astounding 34-41 degrees Celsius (93-105.8 degrees Fahrenheit). In addition, camels can tolerate a high dietary intake of salt, more than eight times that of cattle and sheep. Recent Research Geneticists (Ji et al.) have recently discovered that feral bactrian, C. bactrianus ferus, is not a direct ancestor, as had been assumed prior to the onset of DNA research, but is instead a separate lineage from a progenitor species which has now disappeared from the planet. There are currently six subspecies of bactrian camel, all descendant from the single bactrian population of the unknown progenitor species. They are divided based on morphological characteristics: C. bactrianus xinjiang, C.b. sunite, C.b. alashan, C.B. red, C.b. brown, and C.b. normal. A behavioral study found that bactrian camels older than 3 months are not allowed to suck milk from their mothers, but have learned to steal milk from other mares in the herd (Brandlova et al.)
