The Real Rule of Four

The mind can only remember four things at once. People thought the working memory was seven things (that's why the telephone numbers were seven digits) but now scientists realized we're dumber, sorry, more forgetful than that. This is also the reason why Mau stops at four women because he kept forgetting where to go home and what excuse for whom.

Forgetfulness

Excuse us men if we forget dates, birthdays and many things. Another disadvantage of males: Men were one-and-a-half times more likely to have mild cognitive impairment than women. The prevalence in men increased from 12 percent in men ages 70 to 74 up to 40 percent in the oldest age group, ages 85 to 89. The finding remained the same regardless of a man's education or marital status.

Anger and Decision Making

Angry people were said to be irrational and some of them really are. They get irritated and do some things they would regret the next day. But then some scientists right now are saying that anger can fuel the right decisions. Maybe your brain becomes more focused when you are angry and you tend to become less distracted. Maybe Hulk has a point somewhere. In studies made at the University of California in Sta. Barbara, researchers found that the angry subjects were better at discriminating between strong and weak arguments and were more convinced by the stronger arguments. Those who were not made to feel angry tended to be equally convinced by both arguments, indicating that they were not as analytical in their assessments. The angry students were also better at weighing the arguments appropriately depending on which organization had made them.
