Men Think Clearly Only If They Sleep Alone
According to a study conducted by the researchers at the University of Vienna it was found that sharing a bed diminishes the man's ability to think clearly.
The lead researcher Professor Gerhard Kloesch analyzed about eight unmarried, childless couples in their 20s. They were asked to share their beds and on the next day they were asked to perform a simple cognitive test. It was found that women were fresher than men even when both slept the same number of hours. The researcher said that sharing a bed with a partner temporarily confuses men’s brains and increases the stress hormone levels. On the other hand women do not suffer from this problem.

Now everything seems to make more sense, and on sooooo many levels.
