That health and beauty are linked is not in doubt. But it comes as something of a surprise that who is (36) as beautiful depends not only on the health of a person but also on the average level of health in the place where she lives. This, though, is the conclusion of a study just published in Biology Letters by Urszula Marcinkowska of the University of Turku, in Finland, and her (37) —for Ms. Macink0wska has found that men in healthy countries think women with the most (38) face are the prettiest whilst those in unhealthy places prefer more masculine-looking ones.

Oestrogen promotes (41) , such as large eyes and full lips, that are (42) feminine. Testosterone promotes (43) features, such as wide faces and strong chins.
Previous studies have shown that women with feminine features are more fertile. A man’s (44) for them is thus likely to enhance his reproductive success. Ms Marcinkowska speculates that testosterone-induced behavioral characteristics like (45) , which might be expected to correlate with masculine-looking faces even in women (they certainly do in men), help in the competition for resources needed to sustain children once they are born. But why that should be particularly important in an unhealthy country is unclear.
A. features B. refined C. feminine D. favorable E. modified
