Broadcast live from the hallowed halls of the Anatomy Museum in Trinity College, Dublin, Growing Up, Live continued its fascinating deep dive into the wonders of human life by putting the perplexing facts of adulthood under a microscope.

There's a lot of hearsay about how to find the most compatible partner for you, but science has consistently offered up one solution: smells. Across the animal kingdom, it's found that we are most attracted to others with different immune systems to ourselves so that we create stronger babies. The quickest way to test this is to sniff some sweaty t-shirts. 

In the name of science, Aoibhinn Garrihy put this theory to the test in last night's episode of Growing Up, Live where she was tasked with smelling four such t-shirts and then ranking them in order of preference. 

Watch the video above to see who wore the shirt she found most unpleasant, how a species wildcard affected the experiment and who her scientifically approved partner truly is! 

Growing Up, Live airs on the 13th, 14th and 15th of November at 7pm on RTÉ One.
