I think the name "
Systemic EI" also rolls off the tongue nicely, similar to what
@SOC mentioned earlier.
As in:
Doctor: "I am afraid I have very bad news: you have a nasty disease called
Systemic EI."
Patient: "Oh my God! That sounds terrible."
Doctor: "I am afraid it's worse than terrible;
systemic EI is a disease that will ravage every aspect of your life. It hits both mind and body.
Patient: "Oh sweet Jesus!. What does the 'EI' stand for?"
Doctor: "Exertion Intolerance. It means that every time you try to perform any substantial activity, either physically or mentally, you will get a terrible reaction in both body and mind, which we call post-exertional malaise, or PEM for short. PEM is metaphorically like being hit by a freight train.
