Why do women live longer than men Does the answer lie in biology, nutrition, psychology or sociology - Essay Example This has been attributed to various behavioral and biological reasons. Research indicates a decrease in mortality rates among women in 20th century. The life expectancy gap between various races and people has narrowed significantly, with the gender gap becoming wider. This affects sex ratio, and social and demographic factors like marriage and valuation of pension plans (Reijo & Chen 2013, p. 118). Men are believed to die younger due to stressful lives than women. If this was true, the gap could be decreasing significantly as more women assume jobs that were previously believed to be for men. Also, women get stressed as they work outside home on top of the stresses at home. However, despite women living longer than men, they are less healthy than men at old age. Biologically, women are considered to be more fit than males due to the hormonal and genetic differences (Eskes & Clemens 2007, p. 126). Theoretically, aging results from the gradual accumulation of the tiny faults and damages to cellular components like DNA and protein. Women are believed to have the biological advantage as due to their involvement in reproduction. Women are involved in reproduction for longer than males. Also, it is argued that iron may cause early deaths. The only way to lead out the iron is through blood, which is normally an advantage in females as a result of menstrual cycles. High accumulations of iron raise the toxic level as iron is an oxidizing element that has potential of increasing the heart diseases and risks of cancer (Ginter & Simko 2013, p. 45). Women have 2 X-chromosomes and men have X and Y chromosomes. The second X chromosome in women acts as a backup after the other gene becomes damaged. Recent hypotheses indicate that Y gene is normally toxic and acts as a source for other gene products accelerating aging. Specifically, women have microRNA and X chromosome in their ribonucleic acid. Most microRNA is found in X chromosome,

Causes and effects of Homeless - Research Paper Example The author states that poverty plays the biggest role in rendering people homeless. This is because poverty and homelessness inextricably link. Agreeably, poor people face substantially hard times when paying for their house rent, food, education, child care, and health care among other things (Andersen & Taylor, 2010). Note that, one must make difficult choices especially when limited resources have to cover a number of these necessities. In most cases, according to experts, many people tend to opt for other things instead of housing since housing absorbs much of most individuals’ earnings (Levinson, 2004). A research carried out in 2007by the US Bureau of the Census 2007 found out that 12.5 percent (37.3 million) of the US population lived in poverty. The Bureau asserted that the 2007 findings were not statistically different from those of 2006 in any way (Ravenhill, 2008). Further studies on this subject indicated that increased erosion of employment opportunities for the l arger segment of the American workforce and the declined availability and value of public assistance are the two major contributing factors accounting to increased poverty. Advocates for homeless maintain that violence in homes is a factor contributing to homelessness, particularly in women with children. Facts about the homeless point out that almost half of all homeless youths and adult women with children experienced domestic violence prior to fleeing their homes (Andersen & Taylor, 2010). Nationally, studies reveal that most people who are now homeless could not withstand the kind of physical abuse they experienced in their homes and as such, they opted to run away or rather disappear from their previous settlement (Levy, 2010). Research findings from 2007 showed that of the more than 7,000 people counted during the One Night Count, over 1000 complained indicated that domestic violence is a significant element that contributed to their state of homelessness.
