I have a child that has been admitted to hospital over 20 times with severe illness (bad pneumonia, horrible saturation) with common cold (congenital lung issue).

The common cold is a 1-2 month ordeal with an ambulance ride in the middle. If someone made a pill that just made common colds less severe in the lungs, it would be absolutely revolutionary. Our healthcare system could pay $20k/year for my child to have that and still make money. Heck, I'd pay that out of pocket if they didn't.
