Do men or women wash their hands more?
Do you wash your hands after going to the toilet?
Well not everyone does, according to a survey by Public Health Wales.
The survey shows one in five men in Wales do not wash their hands after going to the toilet.
Gary Winthrope, 30, from Bridgend said: "I've been in the men's toilets and I can tell, I'd honestly say about nine out of 10 people don't wash their hands coming out."
Thousands of adults were surveyed and only 38% of men and 43% of women thought hand washing was necessary.
So what do people in Cardiff think?
