What are the lessons that could be learnt from working at the COVID-19 quarantine zones?

Something interesting that I’ve noticed is that we are all brothers. In the sense that we are all humans, and when the swab goes into the nose, it’s the same for everyone. It’s three and a half inches and it reaches the back of the throat. So we’re all the same. Foreign workers, Singaporeans, PRs. We are all the same. We are here for each other.
