🧠 Why Test Your Brain Age?
Scientific studies suggest that while reaction time naturally changes with age, regular mental exercises can help maintain cognitive sharpness. This Brain Age Calculator provides a fun daily "workout" for your reflexes.
Daily Practice: We vary the tests (Visual Color, Spatial Shape, and Focus Jumps) to engage different cognitive pathways. The more you practice, the more Sparks you earn!
