For my current job we’ve all agreed to take the approach of not writing comments that say what the code does, but why you did something the way you did. Probably about 90% of our code is uncommented because it just doesn’t need to be, but every once in a while you have to do something out of the ordinary to get the desired behavior, and explaining why you made the weird decision you did is infinitely more helpful.
As long as they don’t have different allergies or had biometrics recorded and assigned to them at the hospital it arguably wouldn’t even matter.
