Some people are clever than others in one subject but some in other subjects, so you should not underestimate the qualities and thinking approach. Same in case of choosing and picking some required stuff used at homes is easy for women than men. While on the other hand some stuff which is used in offices and companies may be chosen by men with more perfection., this is just a random thought and opinion and you may deny it if you disagree with me. For example, if you are looking for a dispenser at your home or in an office then maybe the right choice would be different between two customers.
