In this episode, Aleena and Janine get stuck into the research around human crying. Why do we do it? How did this bizarre behaviour even evolve? Why are humans the only animals shedding tears due to emotion? Should we hold in the tears or let them flow? Meanwhile Aleena then shares her newfound appreciation for protective eyewear for doggos and Janine explains how she is attempting to keep her new mobile phone for more than 5 years and nerds out about battery science!
