Nagaoka Shoten Brain training for adults to relieve brain stress: Masterpiece jigsaw puzzles

<Super Deal! Set of 2 Masterpiece Jigsaw Puzzles>
Claude Monet, *Water Lilies*
Johannes Vermeer, "The Milkmaid"
Enjoy jigsaw puzzles of masterpieces by Monet and Vermeer, the "painters of light," while activating serotonin, the happiness hormone that stabilizes mind and body!
It's satisfying when a small piece clicks into place perfectly, isn't it? That's because the brain's "VTA (ventral tegmental area)" is activated. When the VTA is activated, a lot of the happiness hormone "serotonin" is released, increasing feelings of happiness. Also, completing a jigsaw puzzle involves repeating the process of "planning → execution → reflection." As you steadily approach completion through trial and error, your sense of accomplishment will increase, and your stress will naturally subside.
