Over at Mind Hacks, Tom Stafford looks at the scientific literature around onychophagia, aka nail-biting:
Psychiatrists classify it as an impulse control problem, alongside things like obsessive compulsive disorder. But this is for extreme cases, where psychiatric help is beneficial, as with other excessive grooming habits like skin picking or hair pulling. I’m not at that stage, falling instead among the majority of nail biters who carry on the habit without serious side effects.

Even in horrible economic times, a few simple rules hold unshakably true. And one of those rules is that if you possess an in-demand skill, you’ll always find work — and often, at a top market salary, to boot. If you understand Big Data and how to find order from the chaos of massive stockpiles […]
We live in a disposable era. If you can’t fix a broken item with a wrap of duct tape, there’s a very strong likelihood that its next destination is the trashcan. However, that probably leads to a trigger-finger death sentence for many household items that could be saved with just a bit more ingenuity. Before […]
Right tool for the right job. You probably heard a parent or grandparent say it at least once at some point. And it’s true in so many cases. If you spot a small tear in your living room curtains or near to hem a pair of pants, you can always use the good old fashioned […]
