In this brief explanatory video, the speaker describes a Princeton University-led genetic analysis of DNA from over 400,000 individuals in the United Kingdom and Australia. The study found that roughly 1% of adults have never engaged in sexual activity. The researcher suggests a possible genetic link, noting that the same genetic variants associated with higher intelligence and greater educational attainment also appear correlated with a lower likelihood of sexual experience. In other words, the analysis hints that individuals with genetic predispositions toward higher cognitive ability may be less likely to be sexually active.

So researcher at Princeton University analyzed the genes or DNA of over 400,000 people from the UK and Australia and they found something surprising. About 1% of adult never had a experience and for some, that might even have a genetic connection. So gene or DNA is linked to intelligence and education. We're also linked to no. In other words, the smarter the brain, the less likely someone was to be active.
