Recently started working in pharma and this was somewhat of a surprise for me as well having never taken any biology in school - drug approval for bio equivalence has tolerance intervals of like 5-10% - on my first day I worked on some data for an aspirin generic that showed crazy high variance across subjects I think biochemistry might be one of those final frontier sciences we are such a long way from what physics has in the standard model (if the standard model is correct)
