Men flirt to feel fabulous, why flirting gives men a boost.

Researchers recently conducted an experiment to see if men experienced the boost observed in animals known as "mating response".

They put a third of 149 male students aged between 18 and 24 in a room to talk to a 25-year-old male researcher, while the rest spoke to one of seven female students aged 18 to 22.

The men who'd talked to a woman showed, on average, a 14 percent increase in their testosterone levels, while their cortisol levels were up 48 percent. These hormones are associated with alertness and wellbeing.
