Is Casual Sex Bad for You?

Dr. Zhana Vrangalova has some good things to say in this 18-minute long TEDx Talk at the College of William & Mary from 2015: http://tedxtalks.ted.com/video/Is-Casual-Sex-Bad-For-You-Dr-Zh

Some interesting outtakes:

4. There’s an orgasm gap

Armstrong et al., 2012, American Sociological Review
Gender No Orgasm Orgasm
Male 22% 78%
Female 58% 42%

The orgasm gap in romantic encounters is half as large as that in casual sex

“Judgment impaired due to alcohol or drugs is the number one reason for unwanted hookups – hookups you regret the next day … getting smashed? It makes you do things you didn’t want to do, with people you didn’t want to do them with. It diminishes your physiological ability to enjoy sex or perform sex … If you need to be drunk to be hooking up, you should not be hooking up at all.”

Trust, Morality, and Oxytocin

I listened to a TED Talk while having dinner last night. The topic was human morality, and it was presented by a Dr. Paul Zak, who explained his findings on the connection between oxytocin, kindness, and empathy.

Dr. Zak calls oxytocin “the moral molecule,” and believes it’s responsible for trust, empathy, and other feelings that help build a stable society.

An interesting observation from his experiments: high levels of testosterone were found to result in more displays of selfish behavior. The high testosterone individuals would also use their resources to punish others for displaying selfish behavior. Dr. Zak describes oxytocin and testosterone as the yin and yang of morality – “we have testosterone that makes us want to punish people who behave immorally.”

“We don’t need God or government telling us what to do. It’s all inside of us.”

My Sony Playstation Move Navigation Controller Failed …

it’s not dead!

I searched around for a bit to see if anyone else had encountered a sudden failure of their Sony Playstation Move Navigation Controller, and found this thread: sony nav controller wont charge¬†(XIM4 Community). The red LED began blinking once again upon connecting the controller to a USB port on my computer. I’m confused because it had been plugged into the computer’s onboard USB when it failed. No matter. Crisis has been averted.

Leading up to the failure to charge, I’d¬†hardly used the controller or the computer that it was connected to at all. I suspected the battery had drained

Note: The following is the original post. I moved it lower to avoid confusion

Well, it was a surprisingly short run.

It won’t turn back on after an entire night spent on a wall charger.

I aim to find out if it’s gone for good.
