Isaacheunia 

Isaacheunia is chronic and rare lung illness, symptoms include: intense coughing and saying Isaac in between coughs. Isaacheunia coughing episodes can be lethal to short people, long haired blonds, teenage boys with barely present facial hair and individuals with antecedent lung issues. If you show symptoms or qualify to any of the characteristics listed take an appointment with your closest Isaacologue.

I think I have Isaacheunia.
