Knowledge is POWER!!! Are you looking forward to longevity in life? Like living to get 100, then peep this out.

A new study suggests that, for men, your testicles might be holding you back. Korean eunuchs — men who had their testicles removed — outlived their contemporaries by as many as 14 to 19 years, suggesting that male sex hormones somehow act to shorten the male human lifespan, according to a new historical study of records spanning from the 14th century through the early 19th century.

The finding, reported Monday in the journal Current Biology, argues for something called the "disposable soma theory." The idea is that since animals have limited access to energy, there is a natural trade-off between reproduction and the maintenance of the body's cells.

But evidence for the theory has been limited, and some strong counter-evidence exists: Numerous studies in mammals have shown that restricting caloric intake can lengthen the lifespan of some animals — though sometimes such animals become infertile, a fact that may favor the disposable soma hypothesis.

Have you ever wondered why men doze off after they get some? They really do need to sleep after sex because the male brain is designed to switch off at that point, scientists claim.

They scanned men's brains before and during orgasm, and found that the cerebral cortex – or 'thinking' area – shuts down.

Straight afterwards, two other areas, the cingulate cortex and amygdala, tell the rest of the brain to deactivate from sexual desire.

This is accompanied by a surge of chemicals such as oxytocin and serotonin, which can have a powerful sleep-inducing effect, according to the researchers.

Two new surveys break down the sexual minds of African-Americans — such as that 60 percent consider themselves adventurous in the bedroom and over 70 percent are open to using a vibrator with a partner during sex.

The findings were released as part of a Trojan Charged Sex Life Survey of 3,000 Americans nationwide, including ten major cities.

More results among the African-Americans surveyed:

■One in three say the most exciting thing they've done is have sex more than three times in one day.

Would you agree? Does beer really make men smarter? If that's the case, then why do I encounter so many in men in public, drinking beer or other alcohol and they become sloppy drunks! So how smart is that?

Anyhow, a new study from the University of Illinois at Chicago suggests it just might. A group of psychologists found that alcohol can make us smarter, discovering that booze boosts our creative problem-solving skills, which is particularly important for people with linear thinking.

Researchers selected 40 healthy young men for the test. They were split up with 20 staying sober and 20 getting sauced up to 0.07 blood-alcohol level, which is 0.01 short of what Charlie Sheen calls breakfast and what most American states would consider intoxicated.

Not only did the inebriated group solve 40% more of the brainteasers in the test, but they also completed it faster than the sober group.

New research suggests that the use of vitamin C supplements may help stave off gout in men. A report in the Archives of Internal Medicine indicates that vitamin C intake of at least 1500 milligrams per day reduces the odds of gout by 45 percent compared with an intake of less than 250 milligrams per day.

Prior research has shown an inverse link between vitamin C and uric acid levels in the blood, but whether higher concentrations of the vitamin reduces the risk of gout was unclear, according to lead author Dr. Hyon K. Choi, from the University of British Columbia, Vancouver, Canada, and associates.

The findings come from a study of 46,994 men who were followed from 1986 to 2006 as part of the Health Professionals Follow-up Study. None of the subjects had a history of gout when the study began. Vitamin C intake was assessed with validated questionnaires every 4 years and gout was determined using American College of Rheumatology criteria.

During follow-up, 1317 men developed gout, the researchers report.
