Most Gedolim tend to be in poor health. That is because most Gedolim tend to be advanced in age, and human who are advanced in age tend to be in poor health, relative to younger people.
An analogy. In the near future (based on life expectancy for someone her age), Queen Elizabeth will become ill and die. It is quite predictable (even if once upon a time it was considered treason to speculate about the monarch’s mortality). However her subjects will make a big thing out of being concerned and mourning her, not because it is shocking, but because that is part of respect.
Everyone knows that almost all Gedolim are going to expire in the foreseeable future. That doesn’t mean we shouldn’t make a big fuss. They are our royalty, and we should act appropriately.
