title: By the way, doctor. I just got my cholesterol checked, and I'm confused. LDL is bad and HDL is good, so how can they be combined into an overall number that makes any sense? Isn't that like an accountant mixing debits with credits? Wouldn't it make more sense to have a net cholesterol number (HDL minus LDL), or perhaps a ratio?
