Best of 2022: Freeze Tag

Kathryn H. Dao, M.D.

A beloved childhood game I enjoyed was Freeze Tag. Players would run to avoid being tagged by the person who was “It”.  If you were tagged, you had to “freeze” in your spot until someone was brave enough to come un-tag you.  The game ends when everyone is frozen or if people quit. For over 2 years, I have been living in a real-life “Freeze Tag” game and able to dodge COVID19, until now. Sitting in my room symptomatic and frozen in isolation, I ruminated about my patients who had COVID19 and their experiences. I wanted to share with you three stories of three variants. Read Post
