I doubt if many of the grandchildren of these famous people had asthma!
I was born with asthma, pneumonia, bronchitis, and whooping cough and spent the first 6 months of my life in an oxygen tent.
Neither of my parents or my four grandparents smoked and before leaving grade school I achieved 2 Presidential physical fitness awards signed by President Nixon.
Nowadays I am convinced that I would have been labeled an invalid and would be deemed unable to be a productive member of society.
