Mary is a 70-year-old patient who has type 2 diabetes and high blood pressure, and recently she fell down stairs and broke her leg. She visited her family doctor for all these problems. The doctor gave her three different medicines to take: red pills for diabetes that she needs to take before every meal; blue pills for high blood pressure that she needs to take before going to bed everyday, green pills (pain killers) for her broken leg in the morning and in the evening. In addition to that, she needs to stretch her leg every day. After the doctor left, she completely forgets the instructions the doctors give to her. She needs to remember the time to take the medications and the doctors need to know whether she has forgotten any.
