Q: "Physical, speech, and occupational therapy" VS "Physical, speech and occupational therapies"? Instinctively I believe "therapies" makes sense because the sentence is referring to 3 'types' of therapy, but it just rolls off the tongue funny. 
Anyone have a grammatical reason for which is correct?
Thanks!
P.S regarding tagging I wasn't too sure, I never properly learned grammatical rules growing up and just learned English by figuring out what sounded right/wrong.
