Learning! Roundup: Strong Hands/Strong Heart, Gingivitis Causes Alzheimer's, Ask Before You Help, and More!

A roundup of research from the past week, including the fact that married people have stronger hands than non-married people and gingivitis may cause alzheimer's

Joining Hands

Married people have stronger hands than their unmarried counterparts. Men who have been married more than once have the strongest hands of all. Nobody knows why.

Gingivitis and Alzheimer's 

We may have discovered the cause of Alzheimer's, and it's (of all things) gum disease. The bad news is that lots and lots of people have gingivitis. The good news is that they have just begun clinical trials on a drug that blocks the gingivitis' toxins and this drug may also reverse Alzheimer's. WHOA.

Ask Before You Help

A recent event in Detroit highlights a very important principle for anyone who wants to parachute in somewhere and help a community out: the people you want to help have to be involved in the decisions that will impact them. In Detroit, residents turned down free trees offered to line their streets, unless they got to pick what kind of trees they were. You know why? They are the ones who will be living with those trees.

Gender and Pain

You know the whole "man cold" thing? Well, maybe it's because people have been taking men's pain more seriously from the time they were children, and so they just indulged in it! New research shows that adults take pain more seriously in young boys than young girls. I find this especially interesting, as I would have expected it to be the other way around, in an attempt to toughen young boys up. Of course, I would hope that everyone's pain gets taken seriously.

Side Effects of Binge-Watching

Binge-watching shows can change how you see the world, making you more likely to see other people as mean and to be less altruistic overall. The most popular shows to binge, after all, are pretty dark and violent, including Daredevil and House of Cards. (Also, The Unbreakable Kimmy Schmidt, which I would have expected to have a more positive impact on someone's outlook.)
