In that formulation, it would keep my hubby away...he's allergic to perfume.
Of course Dr. Laura jumped on him: Well, duh, 18-year-olds are more physically attractive than 50-year-olds -- to almost any male. You married you wife for better or worse, and you've just noticed some of the "worse" part. Get over it.
Now we learn that not only are young women more beautiful, but they have secret chemicals. What are us 50-year-old men going to do -- except see if we can track some down before Valentine's Day?
Maybe I can convince my wife to let me rub an 18-year-old all over her.
