Men or Women Live Longer??

       
    Recent research has shown some statistic about the women and men life-span that can be argued about women live longer than men. In line with all the statement, there are secrets behind all the portion of women survive longer than men.
      
If female longevity is the product of evolutionary forces, then one might wonder what physiological mechanisms have evolved to support the preferential survival of women over men. As we have mentioned, sex hormones are thought to be important factors in determining the relative susceptibilities of the genders to aging and disease. Less obvious is the contribution that menstruation might make to longevity. Because of the monthly shedding of the uterine lining, premenopausal women typically have 20 percent less blood in their bodies than men and a correspondingly lower iron load. Because iron ions are essential for the formation of oxygen radicals, a lower iron load could lead to a lower rate of aging, cardiovascular disease and other age-related diseases in which oxygen radicals play a role. Indirect support for this theory comes from studies at the University of Kuopio in Finland and the University of Minnesota Medical School. In these studies, male volunteers who made frequent blood donations had less oxidation of LDL cholesterol--a key step in the development of atherosclerosis and heart disease.

      Women also have a slower metabolism than men--a distinction that makes them more prone to obesity. But there may also be an inverse relation between metabolic rate and life span. Evidence of this link comes from animal studies of food restriction, which slows metabolic processes: in experiments sponsored by the National Institute on Aging, monkeys that ate 30 percent less of the same diet as their free-feeding peers seemed to age more slowly.
      Studies of so-called clock genes in microscopic worms have also demonstrated the connection between metabolic rate and life span. Siegfried Hekimi of McGill University has observed that worms with particular mutations in these genes live five times as long as normal animals and have much slower physiological functions. Although it is still not known why men's metabolism rates are faster than women's, it is becoming clear that this difference is present almost from the moment of conception, when male embryos divide faster than female ones. The faster metabolic rate may make men's cells more vulnerable to breakdown, or it may simply mean that the male life cycle is completed more promptly than the female one.
Finally, chromosomal differences between men and women may also affect their mortality rates. The sex-determining chromosomes can carry genetic mutations that cause a number of life-threatening diseases, including muscular dystrophy and hemophilia. Because women have two X chromosomes, a female with an abnormal gene on one of her X chromosomes can use the normal gene on the other and thereby avoid the expression of disease (although she is still a carrier of the defect). Men, in contrast, have one X chromosome and one Y chromosome, and so they cannot rely on an alternative chromosome if a gene on one of the sex chromosomes is defective.
      This disadvantage became more ominous when, in 1985, researchers at Stanford University reported the discovery on the X chromosome of a gene critical to DNA repair. If a man has a defect in this gene, his body's ability to repair the mutations that arise during cell division could be severely compromised. The accumulation of such mutations is thought to contribute to aging and disease.
       There is also increasing interest in women's second X chromosome as a longevity factor in and of itself. Although one of the two Xs is randomly inactivated early in life, the second X seems to become more active with increasing age. It may be that genes on the second X "kick in" and compensate for genes on the first X that have been lost or damaged with age. This compensation could have a sizable influence, as it appears that roughly 5 percent of the human genome may reside on the X chromosome. In recent years the X chromosome has also become the focus of the search for genes that might directly determine human life span.

Jack The Ripper



A well known unidentified serial killer who was active in the largely impoverished areas in and around the Whitechapel district of London in 1888. The name originated in a letter, written by someone claiming to be the murderer, that was disseminated in the media. The letter is widely believed to have been a hoax, and may have been written by a journalist in a deliberate attempt to heighten interest in the story. Other nicknames used for the killer at the time were "The Whitechapel Murderer" and "Leather Apron".
Attacks ascribed to the Ripper typically involved female prostitutes from the slums whose throats were cut prior to abdominal mutilations. The removal of internal organs from at least three of the victims led to proposals that their killer possessed anatomical or surgical knowledge. Rumours that the murders were connected intensified in September and October 1888, and letters from a writer or writers purporting to be the murderer were received by media outlets and Scotland Yard. The "From Hell" letter, received by George Lusk of the Whitechapel Vigilance Committee, included half of a preserved human kidney, supposedly from one of the victims. Mainly because of the extraordinarily brutal character of the murders, and because of media treatment of the events, the public came increasingly to believe in a single serial killer known as "Jack the Ripper".
Extensive newspaper coverage bestowed widespread and enduring international notoriety on the Ripper. An investigation into a series of brutal killings in Whitechapel up to 1891 was unable to connect all the killings conclusively to the murders of 1888, but the legend of Jack the Ripper solidified. As the murders were never solved, the legends surrounding them became a combination of genuine historical research, folklore, and pseudohistory. The term "ripperology" was coined to describe the study and analysis of the Ripper cases. There are now over one hundred theories about the Ripper's identity, and the murders have inspired multiple works of fiction.

NAZI PROPAGANDA


"Propaganda tries to force a doctrine on the whole people... Propaganda works on the general public from the standpoint of an idea and makes them ripe for the victory of this idea." Adolf Hitler wrote these words in his bookMein Kampf (1926), in which he first advocated the use of propaganda to spread the ideals of National Socialism -- among them racismantisemitism, and anti-Bolshevism.
German children read an anti-Jewish propaganda book titled DER GIFTPILZ ( "The Poisonous Mushroom"). The girl on the left holds a companion volume, the translated title of which is "Trust No Fox." Germany, ca. 1938.

Following the Nazi seizure of power in 1933, Hitler established a Reich Ministry of Public Enlightenment and Propaganda headed by Joseph Goebbels. The Ministry's aim was to ensure that the Nazi message was successfully communicated through art, music, theater, films, books, radio, educational materials, and the press.
There were several audiences for Nazi propaganda. Germans were reminded of the struggle against foreign enemies and Jewish subversion. During periods preceding legislation or executive measures against Jews, propaganda campaigns created an atmosphere tolerant of violence against Jews, particularly in 1935 (before the Nuremberg Race Laws of September) and in 1938 (prior to the barrage of antisemitic economic legislation following Kristallnacht). Propaganda also encouraged passivity and acceptance of the impending measures against Jews, as these appeared to depict the Nazi government as stepping in and “restoring order.”
Real and perceived discrimination against ethnic Germans in east European nations which had gained territory at Germany's expense following World War I, such as Czechoslovakia and Poland, was the subject of Nazi propaganda. This propaganda sought to elicit political loyalty and so-called race consciousness among the ethnic German populations. It also sought to mislead foreign governments -- including the European Great Powers -- that Nazi Germany was making understandable and fair demands for concessions and annexations.
After the German invasion of the Soviet Union, Nazi propaganda stressed to both civilians at home and to soldiers, police officers, and non-German auxiliaries serving in occupied territory themes linking Soviet Communism to European Jewry, presenting Germany as the defender of “Western” culture against the “Judeo-Bolshevik threat, and painting an apocalyptic picture of what would happen if the Soviets won the war. This was particularly the case after the catastrophic German defeat at Stalingrad in February 1943. These themes may have been instrumental in inducing Nazi and non-Nazi Germans as well as local collaborators to fight on until the very end.
Films in particular played an important role in disseminating racial antisemitism, the superiority of German military power, and the intrinsic evil of the enemies as defined by Nazi ideology. Nazi films portrayed Jews as "subhuman" creatures infiltrating Aryan society. For example, The Eternal Jew (1940), directed by Fritz Hippler, portrayed Jews as wandering cultural parasites, consumed by sex and money. Some films, such asThe Triumph of the Will (1935) by Leni Riefenstahl, glorified Hitler and the National Socialist movement. Two other Riefenstahl works, Festival of the Nations and Festival of Beauty (1938), depicted the 1936 Berlin Olympic Games and promoted national pride in the successes of the Nazi regime at the Olympics.
Newspapers in Germany, above all Der Stürmer (The Attacker), printed cartoons that used antisemitic caricatures to depict Jews. After the Germans began World War II with the invasion of Poland in September 1939, the Nazi regime employed propaganda to impress upon German civilians and soldiers that the Jews were not only subhuman, but also dangerous enemies of the German Reich. The regime aimed to elicit support, or at least acquiescence, for policies aimed at removing Jews permanently from areas of German settlement
During the implementation of the so-called Final Solution, the mass murder of European Jews, SS officials at killing centers compelled the victims of the Holocaust to maintain the deception necessary to deport the Jews from Germany and occupied Europe as smoothly as possible. Concentration camp and killing center officials compelled prisoners, many of whom would soon die in the gas chambers, to send postcards home stating that they were being treated well and living in good conditions. Here, the camp authorities used propaganda to cover up atrocities and mass murder.
In June 1944, the German Security Police permitted an International Red Cross team to inspect the Theresienstadtcamp-ghetto, located in the Protectorate of Bohemia and Moravia (today: Czech Republic). The SS and police had established Theresienstadt in November 1941 as an instrument of propaganda for domestic consumption in the German Reich. The camp-ghetto was used as an explanation for Germans who were puzzled by the deportation of German and Austrian Jews who were elderly, disabled war veterans, or locally known artists and musicians “to the East” for “labor.” In preparation for the 1944 visit, the ghetto underwent a “beautification” program. In the wake of the inspection, SS officials in the Protectorate produced a film using ghetto residents as a demonstration of the benevolent treatment the Jewish “residents” of Theresienstadt supposedly enjoyed. When the film was completed, SS officials deported most of the "cast" to theAuschwitz-Birkenau killing center.
The Nazi regime used propaganda effectively to mobilize the German population to support its wars of conquest until the very end of the regime. Nazi propaganda was likewise essential to motivating those who implemented the mass murder of the European Jews and of other victims of the Nazi regime. It also served to secure the acquiescence of millions of others -- as bystanders -- to racially targeted persecution and mass murder.

Degree of Happiness- "The Conquer of Unhappiness"


The causes of unhappiness and happiness lie partly in the social system, partly in one’s individual psychology and partly in human nature. Social systems – war, bad political leaders, cruelty and economic exploitation – create a lot of unhappiness. Individual psychology depends on how you are taught when young, how you react/respond to certain ideas and your own experiences in life.
Bertrand Russell’s 14 steps to conquer unhappiness:
1. Don’t be taken in by melancholy
Melancholy is only a passing mood; don’t mistake it for wisdom. Prolonged sadness can lead to mental depression, a sickness associated with suicidal tendency. You must believe that you can change your mood simply by doing something different – play a game or talk to a good friend for diversion.
2. Don’t get caught in the competitive treadmill
Life is always a struggle. You compete in school, in university and at work … always wanting to do better and making more money. You really do not need so much to be happy. You must know when to stop chasing material possessions and learn to be contented. You cannot be happy if you are still greedy for more and more.
Feeling happy is the only true success. Don’t work so hard until you forget how to be happy.
3. Develop the right attitude to boredom and excitement
Everyone has a natural fear of boredom. That is why one always has the urge to find things to do. Very few people can just sit down, do nothing and simply enjoy peace and tranquility (but give it a try!). Do not fear a little boredom for a certain amount of boredom in life is to be expected.
The opposite of boredom is excitement but be careful in seeking it. Incidentally, there is a recent news report from Australia that the easy availability of Viagra and other stimulants has raised the level of sexual activity amongst senior citizens (that is, those over 75) to exceptional levels of excitement. Just imagine that. Excitement is best sought in small doses and in the right places.
4. Make your worries concrete, don’t suppress them
Get a sense of perspective. Ask yourself “what is the worst thing that can possibly happen?” For example if your doctor tells you that your disease is incurable, you must realise that worry will not make you better. The best you can do is to find enjoyment every day for whatever life you have left.
On the other hand though, when you have a difficult problem, do not suppress it because it will not go away by itself. Face it, grapple with it and try to find a way to resolve it. Do what you can and believe that it will be alright when the time comes. Remember! Prolonged worrying can cause mental depression.
5. Don’t envy, admire!
Since I have already touched on envy and jealousy at the start of my talk, I only wish to add this: Enjoy what you have for its own sake. Don’t compare yourself with others who are more successful than you.
When you are sad, compare yourself with people who are in a worse situation.
6. Fight back against guilt and shame
When you are young, you are easily influenced by your religious teachers and your parents. As a result, your conscience is formed. Many things you like to do but are considered sinful will make you unhappy as your conscience pricks you. Unless you are able to change your mindset, you will be unhappy.
According to Bertrand Russell, consensual sex between two adults can be very thrilling and the partners should not be made to feel ashamed or guilty. Russell expounded this concept almost a century ago. Today a majority of the people – at least in this auditorium – are prepared to accept the idea. A minority though would think that Russell was encouraging divorce as he was an atheist.
Statistics show that more than 50% of people in Europe and the US are divorced. Frequently many marriages that are unhappy do not end in divorce only because of the constraining factors of religion, children, guilt and shame. So to be happy, you need to understand and appreciate Russell’s philosophy on this issue.
7. Don’t suffer from an exaggerated sense of injustice
We must be concerned about politics because it affects all of us in so many ways and impacts on the future of our children. But you must bear in mind that you alone cannot change the situation or the flow of current affairs. After you have done what you can, leave it to fate and don’t be unhappy.
8. Don’t care too much what others think
“Respect public opinion only to avoid starvation and jail.”
Normally you will not feel happy to do something without your spouse’s approval, or that of friends and family. But you must not be afraid to exercise your own judgment in certain important matters, e.g. when to buy and when to sell shares. Your wife may not be giving the best advice on these matters.
Everyone has his own opinion but who is right and who is wrong is a constant puzzle. For example, the Catholics forbid divorce but it is allowed by the Muslim and the civil courts.

The secrets of happiness

Now you must know how to conquer happiness. The next six measures make up Steps 9 to 14 of the Bertrand Russell philosophy to happiness.
9. Cultivate zest
Get into the habit of taking a lively and friendly interest in everything. The more things a man is interested in, the more opportunities he has to make himself happy. An introvert cannot be happy. Outside working hours, you must have a lot of free time to make yourself happy. Make new friends, have more hobbies, play games, surf the Internet, watch football and movies, etc.
10. Be affectionate
Do not be afraid to show kindness and affection to people e.g. tipping waiters and the jagakereta. You cannot be happy if you do not have the feeling that you are doing something good and people love you. You will feel happy if you can make someone happy.
You can create happiness by offering scholarships to help needy students without expecting anything in return. I have done so and found happiness in this. All the recipients have to promise me is that when they are financially solvent they will help other needy students. In this way, they will continue to do charity and create happiness after I die.
Avoid an argument because no one wins in any argument. Remember how you felt the last time you had an argument with someone. When you receive affection or admiration, you would feel secure and this enables you to perform better. By the same token, you should do the same unto others.
Here I would like to quote from Russell’s book again. “The best type of affection is reciprocally life-giving: each receives affection with joy and gives it without effort, and each finds the whole world more interesting in consequence of the existence of this reciprocal happiness. There is, however, another kind, by no means uncommon, in which one person sucks the vitality of the other, one receives what the other gives, but gives almost nothing in return. Some very vital people belong to this bloodsucking type. They extract the vitality from one victim after another, but while they prosper and grow interesting, those upon whom they live grow pale and dim and dull.”
11. Be a good parent
Give your child time and not too much money.
The bond between parents and children is often one of the greatest source of happiness. But in many cases, it is also a source of unhappiness to both parties. In fact, studies show that in most cases, at least one of both parties is unhappy in the relationship. The reasons for this phenomenon are too many and varied and would be outside the scope of this talk.
12. Do interesting, varied and constructive work
Living in a competitive world, one is born to do work. Everyone needs to work. Work prevents boredom. Even uninteresting work will make holidays more enjoyable. Work offers the opportunity for you to achieve your ambition. Try to find interesting work so that you can enjoy doing it.
13. Cultivate plenty of relaxing minor interests
Enjoy as many hobbies and pursuits as you can; make sure these provide a difference from your day job. For example: Keep a dog, read, surf the Net, play games, watch TV or contact your friends more frequently. You must realise most of your enjoyment is generated from the people closest to you – your friends, children and your spouse.
14. Find the right balance between effort and resignation
A man occupies almost all his time in worrying about his wife, children, his work and his financial position. All these burdens are bound to depress and tire him.
Very few people, except singles, have never quarreled with their spouses. Very few parents have not endured grave anxiety when their children are ill. Very few businessmen have never met financial difficulties and few professional men have not faced periods of failure. It is at such times that the wide variety of cultivated interests provides an outlet for amusement and happiness.
