Mentally active people are healthier and live longer. Therefore, in old age, not only physical activity is important, but mental activities also come to the forefront. In the proven holistic brain training (HBT), perception, coordination, and concentration exercises are interconnected through memory tasks, puzzles, and light movement exercises. All exercises are well-tested in practice. They also provide topics for conversation, good mood, as well as mental and physical stimulation. Additionally, therapeutic biographical work can be integrated. Seniors, caregivers, nursing staff, and relatives have the opportunity to select suitable exercises and activate them flexibly in terms of time. Above all, having fun is essential! Because joy and experiences of success evoke positive feelings, they relax and motivate one to continue.
