I saw a story today that suggests women are better off sleeping with dogs. Apparently the study found that women feel more comfort and security from their 4 legged friend than from their significant other.  There was also evidence that women who sleep with their dog have better sleep habits with a more regular sleep schedule.

For me, other than the one obvious draw back, I prefer to sleep alone.  I like to sprawl out and not have to worry about my ridiculous snoring disturbing anyone else.  If you're the type who likes a little platonic partner in the bed with you, maybe you need to adopt a dog.  Oh, and specifically a dog; the same study says that you actually sleep worse with a cat than you do with another human.
