Having This Much Sex Might Make You Smarter

Okay, so there are tons of reasons why you should have sex right now. But here’s one you might not have thought of: Having frequent sex might boost your brain, researchers from Coventry University in the U.K. suggest.

In the study, researchers asked 73 older adults how often they had sex, and then had them perform tasks that tested their brain function—including things like attention, memory, fluency, language, and visuospatial abilities.

How Eating Olive Oil Can Boost Your Memory

You now have one more excellent reason to shelve the store-bought dressing in favor of the homemade stuff: Eating a diet rich in extra-virgin olive oil may protect your brain as you age, researchers from Temple University suggest.

In the study, researchers genetically modified mice to express three key characteristics of Alzheimer’s disease: memory impairment, the buildup of sticky proteins called amyloid plaques, and tangles of tau proteins. Then, when the mice reached six months of age, they had some mice eat chow supplemented with extra-virgin olive for six months, while the others ate their regular food. This food change occurred before the mice began to exhibit signs of Alzheimer’s.

Do You Like Big Breasts?

Are you a breast man? Butt man? Or do legs drive you wild? Your preference is about more than whether you had a Heather Locklear or Pamela Anderson poster above your bed as a teenager.

The First Thing You Must Do in Bed

Generosity for the win: Focusing on what she craves in the sack also increases your arousal, says research in the journal Social Psychological and Personality Science.

Researchers studied “sexual communal strength”—the willingness to meet a partner’s sexual needs—in long-term couples. Both parties filled out daily sex surveys for 3 weeks. Four months later, generous lovers  reported higher levels of daily arousal AND more desire for their partner than the less-generous couples.

Sex Tip: Touch Her Here

There are ways to be touched that are brilliant and other ways that are kind of blah. If there's one thing we know about the way people touch each other during sex it's that they often touch their partner the way that they, themselves, like to be touched rather than finding out how their partner likes to be touched.

Although there's a lot of variability in how people like touch, it tends to be the case that men - whose genitals are covered in skin and less sensitive than women's - tend to prefer rougher forms of touch. More thrusting, more vigor. Whereas women - whose genitals are more vulnerable and some ways and more sensitive  in some spots (hello, clitoris!) - tend to prefer less aggressive touch. Women often prefer gentle tongue flicks on the clitoris or gentle but first stimulation of their genitals. Again, this isn't always the case - there are no clear gender rules in sex - but generally speaking this is often how things fall out.

Bad News About Your Concussion

BY JESSICA GIRDWAIN, 

Hits to the head could hurt later: Concussions may put you at risk for Alzheimer’s later in life, according to a new Mayo Clinic study.

The research found that people with cognitive impairment who also experienced past head trauma had 18 percent higher levels of amyloid plaques in their brain —plaques that are hallmarks of Alzheimer’s—compared to people without a history of brain injury.
