Leaving the house looking like you just got out of bed and grabbed the first thing you saw lying on the floor. Here's another little statistic for you guys. That's right, most women don't like men with mustaches and beards. The only time that a positive percentage preferred facial hair is when the men in question were bald. Neat hair frames the face and draws more attention to your better features, so it may be a good idea to not have hair that looks like you just rolled around in the dirt.
Dental hygiene is pretty self explanatory.
You never know when the cook might slip some garlic into your food. So you've got your hair cut, your face shaven, and your teeth clean. Do not, and I repeat, do not bathe yourself in cologne. That is bad, bad ,bad, fellas. You want to give off just enough of a scent to make the woman smell it when she gets close to you.
