The geeks are inherent at birth: older men have geekier sons, study finds

Researchers claim boys born to older fathers score higher on a scientifically devised 'geek index', which takes in non-verbal IQ and social aloofness

Older men tend to have "geekier" sons who are more aloof, have higher IQs and a more intense focus on their interests than those born to younger fathers, researchers claim.

The finding, which emerged from a study of nearly 8,000 British twins, suggests that having an older father may benefit children and boost their performance in technical subjects at secondary school.
