I have had it. BAD. The Mrs also.
....add me to that BAD case of mumps also.
I had them as a adult and mother of two children.
They dropped on me into the pancreas gland and made me violently ill.
Mumps are nothing to sluff off as a minimal disease.
It took me 3 months to get up and on my feet.
Me and one of my brothers had it as kids. Pretty miserable for about a week. Other siblings had received the Mumps/Measles/Rubella shot, me and the unlucky brother got the Measles/Rubella shot.
When you open the doors to the third world what did they expect
uh-oh — Never had mumps, and I am in my 60’s.
