At risk means you have a higher chance than normal to be affected by a certain disease.
What the focus is when you say “at risk” is factors that will increase your chances of getting covid.
Since all of us living (hopefully) have lungs, there’s a baseline level of risk and is pointless to point out. We only mention at risk when there’s special factors other than “lungs” that increase our chance of getting a disease. By following this logic by simply being human you are at risk of diseases so the only way to not be at risk is to die
With this attitude there is no way in hell you should or could be the leading authority on human conversation.
It’s called social anxiety. I’m so sorry someone being anxious is inconvenient to you.
