My husband Thom grew up in a very religious household. A questioner by nature, he struggled to grasp what he was told without constantly asking for evidence. But one thing he heard stood out as absolutely true. Without a doubt, he knew deep in his heart and soul that the most prized possession on Earth, more precious than gold or jewels, had to be wisdom. The certainty of that awareness never wavered. As it turns out, new research appears to confirm that obtaining wisdom just might be central to what leads to a happy and healthy long life—in other words, a key to positive aging. And it’s likely that treasure is something all of us would like to experience in the years to come.
