Old minds are like old horses; you must exercise them if you wish to keep them in working order.

Summary

This quote suggests that our minds, like horses, require regular exercise to stay functional. Without regular stimulation and activity, our minds can become stagnant and less effective. Just as horses need physical exercise to remain strong and healthy, our minds need mental exercise to stay sharp and engaged. By actively stimulating our minds through learning, problem-solving, and engaging in intellectually challenging activities, we can ensure that they remain in good working order, allowing us to continue thinking and functioning at our best.
