Mary is a retired Secretary and travel organiser. She lives on her own, but has a daughter and grandchildren living nearby. Mary likes to keep very active during the day and helps with looking after the grandchildren. She also attends Keep Fit and Tai Chi and likes to sew and do crafts. Mary believes sleep is very important and would like to have more sleep, but also feels that she doesn't want to waste time sleeping as there are so many things she enjoys doing.

Sue B. lives on her own in a small, friendly village. She has 4 children and 7 grandchildren. She recently gave up her job as a provider of supplies to pre-school groups, but still works part-time making scarves which she sells through Craft Fairs. Sue B. is very active, often taking several walks a day, sometimes swimming and bicycling. She is also a retired Church Warden. Sleep is very important to Sue B., and she loves waking up after a very good night's sleep.

Mary often finds it very difficult to get to sleep, sometimes taking up to an hour to fall asleep. Mary finds that relaxation and meditation exercises help her to fall asleep, and help her get back to sleep if she wakes up in the night. Even if she has not had a good night Mary finds it impossible to take a nap during the day, although she may put her feet up in bed to have a rest instead. Mary hasn't been to the doctor about her sleep, but has tried some over the counter remedies.
