What is the difference between "should X" and "should be Xing" in the following contexts? Or are they interchangeable?

  • 10 Things you should do to improve the health of your hair.
  • 10 Things You Should Be Doing to Boost Your Immunity.

(From Google searches.) Is there any slight difference between using should do and should be doing there?


I believe in making the world safe for our children, but not our children's children, because I don't think children should be having sex.
— Jack Handey

Would "I don't think children should have sex" be possible here?

If you were my boss at work and you said "here are 10 things you should do", I would assume these were new projects, not yet undertaken, to put on the "to do" list.

If you said "here are 10 things you should be doing" I would be more likely to feel a sense of immediacy with an implied "should be doing NOW".

I would assume the writer of the second article title wished to convey a sense of urgency.

My sense of the difference is this:

Ten things you should do implies that the list will consist of things that you do once, and then you're done; for example, "lose 10 pounds" or "get your prostate checked."

Ten things you should be doing implies that the list consists of things that you have to develop as ongoing habits; for example, "get 30 minutes of exercise every day."

This distinction can easily be overridden by the details provided in the actual list, though.

What you "should do" means "the task is assign to you to accomplish" but what you "should be doing" means "it was assigned earlier on and I left it when in for something else".
