Hey, women, rejoice! When you get older you're less bitchy (to each other).

An experiment published in Biology Letters has been interpretted by the press in different ways. The Daily Mail: "Women over the age of 50 may be less frisky, less nimble and less cute but, as if by way of compensation, they are also a lot less bitchy." The Telegraph: "So today’s research published in Biology Letters, that finds women become less bitchy when they are older, is frankly, unsurprising. The mistake however is that the researchers thought the decline in bitchiness came post-menopause, when they should have set the benchmark as post-puberty." Dr. Petra Boynton's take: "If we don’t take action we’re going to keep on seeing this carnival of poor sex science being promoted. With poor media coverage following as a result."
