Benjamin Rein, 10, penned a sweet thank you to those on the front lines helping people get through the COVID-19 pandemic.
"This is a very hard time in the world right now," the note began. "Everyone should stay calm. You are all working so hard and because of you, we are going to beat the coronavirus soon. Thank you for all the work you've done."
"You guys are like superheroes," he continued. "Braver than Batman. Stronger than Superman. And faster than The Flash. You can get any job done."
Benjamin ended the letter, which was addressed from him to doctors and nurses, by sending all of the medical professionals out there his "best wishes."
Elsewhere in the social media post, Brady, 42, and Bündchen, 39, shared a video in which they pay tribute to healers for all their "dedication, courage and love."
