processing it gave me greater empathy for everyone going through this, the uncertainty. i think there's a tension between the data-driven doctor part of me and the emotional dad part of me what was the morning after he got sick. i called him at 9:00. he didn't answer. 10:00, he didn't answer. he's relatively low risk, but it crossed my mind is he okay? is he dead? i kind of broke into his apartment to be sure he was breathing. >> it's scary. you're not a doctor then. you're a dad and then a doctor. right? so is there something that you take away that you can tell other folks because there are so many of them watching now who are going through the same thing with family and friends or maybe themselves? >> yeah. first of all, you know, it's okay to feel all of these emotions. but the key thing is the risk for most people, although not all, but he's got three -- has had three vaccine shots. the risk that something terrible is going to happen is very low. not to overreact.
