According to the Daily Telegraph on January 7, marrying someone much younger only makes you seem older in the eyes of everyone else, shows an academic study.
When someone see a mature man with a woman half his age, they estimate him to be much older than it really is because of the obvious gap, said the study.
Psychologists from Jena University in Germany discovered that a person's perceived age varies depending on the people they are with.
They carried out a series of research projects called Person Perception to see how people estimate the age of others.
If they see a person on their own then most observers are fairly good as estimating that person's age. And the same applies if there is a group where everyone is around the same age.
But if most of a group are old and one person is young, that difference is exaggerated and those trying to guess the individual's age are "consistently wrong" said the research.
