I have some thoughts. Aging? Windows? Diet? Daniel Kolitz wants to know, too.

If you’re like me, you can barely read this paragraph right now. I’m amazed I’m even capable of writing it. Most of us suffering from brain fog can recall a time, perhaps illusory, when setting and achieving goals was simple, more or less—when the main impediments to accomplishment, or simply making breakfast, were external to ourselves. We wonder: how did it happen? Is it aging, or luck, or diet, or what? Can it be reversed?

A variety of scientists, professors, and researchers chimed in but nobody came up with an actual definition.

I think it’s children.
