Its a birth defect
You obviously miss the point that he never had asthma to begin with. Mikey was a hypochondriac.
I thought it was more likely he got panic attacks. Hey! You're not old enough to drink! Now go and die for your country!!!
Asthma can develop at any age. Hail to the king, baby.
Ohmygod, you're dumb. I "came down" with my form of asthma at 40.
Agree but basically he was already using a inhaler and going out in bad weather can make breathing worse ie cold, lung infection etc. End of line
It was just a funny line.
