This seems utterly bizarre to me:
People, and especially men, hate being alone with their thoughts so much that they’d rather be in pain. In a study published in Science Thursday on the ability of people to let their minds “wander” — that is, for them to sit and do nothing but think — researchers found that about a quarter of women and two-thirds of men chose electric shocks over their own company.

When it became clear that people were desperate for distractions, the researchers decided to give them one. “It dawned on us: If people find this so difficult,” Wilson said, “would they prefer negative stimulations to boredom?” He gave them access to a device that would provide a small electrical shock by pressing a button. It wasn’t a very strong shock, as the device was built around a 9 volt battery. “But we weren’t even sure it was worth doing,” he said. “I mean, no one was going to shock themselves by choice.”
But they did. The researchers removed the curiosity factor by giving subjects a sample shock beforehand. They even asked them how much they would pay, given a $5 allowance, to prevent another shock. Most offered up a hypothetical dollar or two. But when left alone in the room for a 15-minute thinking session, the participants exhibited some shocking behavior. One man (whose data was left out of the study) shocked himself 190 times. “I have no idea what was going on there,” Wilson said. “But for most people, it was more like seven times.”
I find "alone with my thoughts" time not just tolerable but necessary. The mind doesn't have to wander all that long, but time spent not thinking about the next thing to think about really clears away the clutter. For some reason, however, people tend to get annoyed when you let your mind wander during a conversation. Best keep it a solitary habit.
