1. Dear Author had posted a link to an article about guys with guitars being hotter, per a recent study. Intrigued, I did a little more digging and found this article which, among other things mentions that the study is very preliminary and that the comparison was between a guy holding a guitar and a guy holding a sports bag (which I think was supposed to indicate that he was sporty, and not, you know, carrying around a bag big enough to fit a person) and that really, the guy with a guitar had a higher success rate, but it was still only a 30 percent success rate.
2. Choir singing may reduce anxiety. Now they compared it to doing nothing, not just singing by yourself, but there seems to be something to this group singing thing. (And yes, my biases may be showing here.)
3. And as reality TV watchers who have seen contestants who do great in silly challenges only to fizzle in the go out and do great finale know, imposing limits can actually enhance your creativity.
