Women lead way on office hygiene

Men's offices are dirtier than women's with significantly higher numbers of bacteria, a study has found.

Much of the reason is probably down to hygiene, say the researchers from San Diego State University.

The scientists took 450 swab samples from 90 offices across the US. They wrote in the online journal Public Library of Science ONE: "Surfaces in offices inhabited by men were consistently more contaminated than those of offices inhabited by women."
