The competitive aspect of jigsaw puzzling dates back to the 1980s in the US, when Hallmark ran a national competition for several years. In 2022, the volunteer-run USA Jigsaw Puzzle Association partnered with Ravensburger to bring back a national championship.
If you're going to prioritize one thing for your brain health, make it this: regular aerobic exercise. Multiple large-scale studies show that aerobic exercise doesn't just keep your heart healthy-it directly impacts your brain structure. One year of aerobic exercise in older adults led to significantly larger hippocampal volumes and better spatial memory. Other trials documented that exercise actually slows age-related gray matter volume loss.
It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity, and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles.
Think of your creativity like a high-performance garden: If you focus only on the visible harvest (outputs) and never allow the soil to lie fallow (liminal space) or the bees to roam freely (play), the ground eventually becomes depleted. Boredom is the signal that the soil needs replenishing, ensuring that your next season of work is a flourish rather than a struggle.
