Your doctor recommends a thing, and you do it. That’s the simplest version of how the doctor-patient relationship might go, but it’s not always the best one. You may find out later that there were other options for treatment that you never knew about, or that the drug you took has risks that may outweigh its benefits.

When kids are between two and four, they're bubbling with questions — preschool children ask their parents an average of 100 questions a day. (My daughter seems to ask this many on the drive to school — How do the cars stay in the lines? Who makes the lights change colours? Why don't they make a wall so the bicycles can't get hit? Why do motorcycles get to go in front of us? She is very much into the inner-workings of street traffic these days.)

Your role at the doctor's office isn't over when you describe your problem. You have to understand what your provider is telling you -- and that goes double if you're signing a form to say you understand the risks of a procedure or of being involved in a study.

Job interviews can be tricky, especially when you get hit with the dreaded "tell me about yourself" portion. There are a few things you should always include in your response, but it's also a good time to cleverly work in things that point to your strengths.

When you're clueless about a topic, asking questions about it can make you feel dumb. However, despite how you feel, asking good questions actually makes you seem smarter. This video breaks down research that supports this very concept.
