Does size matter to women? What about height? These age-old questions have been asked by every man who has ever lived. What does science have to say?

It’s episode 10! In this milestone episode, Lu and Tirth pay homage to some of the greatest scientists of all time, fiercely debate whether size matters to women when it comes to the attractiveness of men, and discuss whether brain size in birds correlates with the probability of getting run over by cars.
