Women enjoy best sex at age 28

A new survey has found that women have the best sex of their lives when they are aged 28, but men don’t reach their peak until they are 33. The study also found that women have the most sex at 25 and lose their virginity at aged 17. Men, who on average lose their virginity at 18, are most active when they are 29, the Sun reported. Asked when they had their best sex, 40 per cent of 1,281 people aged 28 polled said now. And those in their 50s and 60s said they had their best sex aged 46. The results contradict research, which says men reach their sexual peak at 18 and women at 30.

The survey by online sex toy retailer lovehoney.co.uk also highlighted a shift towards losing virginity earlier. It found the average age of virginity loss was 17 for those in their 20s, 30s, 40s and 50s, but those in their 60s waited until they were 18. Relationships expert Tracey Cox, 51, who has her own range of sex toys with Lovehoney, said that this finding destroys the myth that it takes women longer to master their sexual responses. Despite the female sexual system being far more complex than a man, women are discovering what works and doesn’t faster than men.

Kindle Fire has sold out, says Amazon

Amazon.com Inc said on Thursday its Kindle Fire tablet computer is sold out, raising expectations that the world’s largest Internet retailer will launch at least one new version of the device at an event next week.
Amazon Chief Executive Jeff Bezos said the 7-inch Kindle Fire has grabbed 22 per cent of US tablet sales since it hit stores in November at $199, well below the price of Apple’s market-leading iPad.
Amazon is holding a media event on September 6 in Santa Monica, California, fueling speculation that it will launch new tablet devices.
We have an exciting roadmap ahead,” Bezos said in a news release. “We will continue to offer our customers the best hardware, the best prices, the best customer service, the best cross-platform interoperability, and the best content ecosystem.”
Less than a week after Amazon’s event, Apple is planning a news conference where it is expected to unveil a new version of its iPhone. However, some analysts also expect Apple to launch a smaller tablet this year to compete with the cheaper Kindle Fire.
The tablet market is among the fastest-growing sectors of the technology industry. Research firm Gartner is forecasting tablet sales almost to double this year to 118.9 million units. That has lured many of the largest technology companies.
Google Inc recently introduced a 7-inch tablet called Nexus 7, which has been selling well. Microsoft Corp is expected to launch its Surface tablet later this year. Barnes & Noble Inc’s Nook tablet, introduced last autumn, has also been popular.
Amazon said only that its Kindle Fire was sold out. It did not indicate when the device would be back in stock, or how many it has sold. An Amazon representative was not immediately available for further comment.
Since the launch of the tablet last year, Amazon’s top-selling products have all been digital items such as music, videos and movies, it said.

Healthy lifestyle adds 6 yrs to your life

People who follow a healthy lifestyle live up to 6 years longer compared with those with a high risk profile, reveals a Swedish study.

Living a healthy lifestyle into old age add five years to women’s lives and six years to men’s, the study found.

This is the first study that directly provides information about differences in longevity according to several modifiable factors, said researchers.

It is well known that lifestyle factors, like being overweight, smoking and heavy drinking, predict death among elderly people. But is it uncertain whether these associations are applicable to people aged 75 years or more.

So a team of researchers based in Sweden measured the differences in survival among adults aged 75 and older based on modifiable factors such as lifestyle behaviours, leisure activities, and social networks.

The study involved just over 1,800 individuals who were followed for 18 years (1987-2005). Data on age, sex, occupation, education, lifestyle behaviours, social network and leisure activities were recorded.

During the follow-up period 92 percent of participants died. Half of the participants lived longer than 90 years.

Survivors were more likely to be women, be highly educated, have healthy lifestyle behaviours, have a better social network, and participate in more leisure activities than non-survivors.

The results showed that smokers died one year earlier than non-smokers. Former smokers had a similar pattern of survival to never smokers, suggesting that quitting smoking in middle age reduces the effect on mortality.

Of the leisure activities, physical activity was most strongly associated with survival. The average age at death of participants who regularly swam, walked or did gymnastics was two years greater than those who did not.

Overall, the average survival of people with a low risk profile (healthy lifestyle behaviours, participation in at least one leisure activity, and a rich or moderate social network) was 5.4 years longer than those with a high risk profile (unhealthy lifestyle behaviours, no participation in leisure activities, and a limited or poor social network).

Even among those aged 85 years or older and people with chronic conditions, the average age at death was four years higher for those with a low risk profile compared with those with a high risk profile.

In summary, the associations between leisure activity, not smoking, and increased survival still existed in those aged 75 years or more, with women’s lives prolonged by five years and men’s by six years, the researchers said.

War of words on the origin of words

Professor Bhadriraju Krishnamurti, a scholar and gentleman, and former Vice Chancellor of the University of Hyderabad, breathed his last a fortnight ago. His demise marks the end of an era in the scholarly analysis of Indian languages. His authoritative book “The Dravidian Languages” (Cambridge 2003) clearly set out the origin, development and diversity of the Dravidian languages.

He made me aware of the point made by the geneticist Luigi Cavalli-Sforza that the genetic tree and the linguistic tree have many impressive similarities, and would goad me into thinking more about these putative similarities.

True, DNA is the seed on which the genetic tree has grown, flourished and diversified. Likewise, word is the seed on which languages form, flourish and multiply. Just as genes are sequences of DNA and the collection of genes (the genome) identifies an organism, words, phrases, sentences, and grammar define language.

Just as organisms have evolved from an ancestor, languages too have evolved from an ancestral or “proto” language. Where and how did the ancestor of all Indo-European languages, or the proto-Indo-European, originate and diversify into German, Italian, Russian, Persian and Hindi, is a question on which there has been a controversy or war of words.

In this connection, Professor Krishnamurti would have been interested in a recent paper in the August 24, 2012 issue of Science by Dr. Quentin Atkinson and colleagues of the University of Auckland, New Zealand.

Sperm from skin ups fatherhood hopes

Scientists claim to have successfully created early-stage sperms from human skin that could potentially help infertile men, including survivors of childhood cancer, fulfill their dream of fatherhood. The breakthrough, which came by unlocking the intricacies of male reproduction, could also lead to new contraceptives and a ‘miracle pill’ to treat infertility, they say.

For the study, the American scientists used a cocktail of chemicals to wind back the ‘biological clock’ in skin cells, turning them into cells with the chameleon-like powers of embryonic stem-cells, the ‘Daily Mail’ reported. They then used a combination of nutrients to coax them to develop into round cells which were just a few steps away from mature sperms and appeared genetically normal.

The University of Pittsburgh School of Medicine team, led by Dr James Easley, believe they have cracked the most difficult part of sperm development.

This means that by altering the procedure it should now be relatively easy to get to the next stage – elongated cells that, while yet to grow tails, should be able to fertilize eggs.

The technique is still many years away from use in clinics, however, the science is fraught with moral and ethical concerns.

Critics argue that it is wrong to meddle with the building blocks of life and warn of a future in which babies are created through entirely artificial means. Scientists have already succeeded in coaxing embryonic stem cells, which are master cells plucked from embryos in their first days of life, turning them into sperms.

Using skin as a starting point would be more ethically acceptable as it would also mean the sperm would have the man’s genes. The study was published in the journal ‘Cell’.
