 Those who fulfill the inclusion criteria and are willing to participate in the study, will receive postal information of the study, two items of informed consent forms, questionnaires to be filled at home baseline data, and a short description of eight entertainment games to be used if allocated into the control group. Further, possible participants are aware that after 1-2 weeks they will receive another call from the Research Assistant. This will ensure that possible participants have enough time to read all material, ask questions, and make their decision whether to participate in the study or not and what type of game they would like to play if allocated into the control group.
