You bought it to get lucky, but she left after dinner.
In a study from the University of Liverpool, researchers had one group of men spray themselves with a fragrance they found appealing, while another group received a placebo scent. The researchers asked the men to evaluate their emotional state over a period of several days, and also asked a group of women to watch short, silent video footage of the men and rate their attractiveness. Turns out, the men who used the good-smelling fragrance reported higher levels of self-confidence, and the women who viewed the videos rated those men as more desirable. What this means for you: If you bought cologne because the advertisement said chicks dig it, but you actually don’t, your date will default to your reaction — not the scent itself. Choose a scent based on your taste, not someone else’s.
