According to research compiled by Coventry University and Oxford University, being more sexually active as you age can make you more intelligent.
Those who had sex more often, scored higher on tests that measured their verbal fluency and their ability to visually perceive objects and the spaces between them.
The study, published today in The Journals of Gerontology, Series B: Psychological and Social Sciences, involved 73 people aged between 50 and 83.
Participants filled in a questionnaire on how often, on average, they had engaged in sexual activity over the past 12 months – whether that was never, monthly or weekly – as well as answering questions about their general health and lifestyle.
The 28 men and 45 women also took part in a standardised test, which is typically used to measure different patterns of brain function in older adults, focussing on attention, memory, fluency, language and visuospatial ability.
This included verbal fluency tests in which participants had 60 seconds to name as many animals as possible, and then to say as many words beginning with F as they could – tests which reflect higher cognitive abilities.
