Today's interesting fact has to do with our default level of feelings.

Everyone seems to have a default setting when it comes to being happy, sad, miserable, grumpy or what ever. An individual will leave that setting, become happier, sadder, depressed, etc but eventually they will return to their default setting. Most of our time is spent in that setting.

Researchers have for years been trying to determine when this setting becomes our default. All the recent research suggests that this setting is determined at around 3 years of age, and it usually remains the same throughout life. The only times it changes is due to physical trauma to the brain, viral or bacterial infections, or chemicals changing the function of the brain.
