Sunshine Might Help Love Bloom, University of South Brittany Study

People looking for a date might want to wait for better weather. Flirting is most effective when the sun is shining, according to new research conducted in France. The study involved an "attractive" 20-year-old man who approached women aged 18 to 25 walking alone in the street and asked them for their phone number. These advances were made on both sunny and cloudy days when the temperature was about the same.
