People are attracted to other people who are good looking, and this is part of the way the brain is wired. Any potential mate is screened for looks as well as other survival factors. Modern man may have passed by the need for this type of screening, but the ancient parts of the brain are far behind the times. It takes a person who uses their brain to discover the difference and discount looks as criteria for choosing a date.
Getting past the way a person looks is not always easy, but many people are willing to give it a try. It often helps if they know the person through other social contacts, and a date is not their first meeting. If they come to see the person as intelligent, kind and open to new experiences, this may help a single person discount their looks and choose to ask them for a date.
