John, thanks a million))) I have one more note and if it's possible check it please)))

We have runny noses. We have headaches. The have coughs. Consider if the thing spoken about is shared or individual. Do they each have this, or do they share it. You cannot really share a runny nose. But some things can be shared literally (like a car) or conceptually (like time). So you could say we have a car or we have no time. But an illness or medical condition would typically be individual.
