What is the definition of Solely Medical Research?

" Solely medical research is like that one friend who only talks about their latest science experiment - never once mentioning your actual problems. It's like they've found a rare, rare medical condition that none of their research papers have ever touched on, leaving you feeling more confused than ever."
