A Curious Question

When you are a kid, you are always asking questions: Why does the sun come up? Why is the grass green? Why is the sky blue? How does a car work? How does this computer work? What is the best way to do this?

At some point along the way you lose that curiosity. You stop learning and, worse, you stop wanting to learn.

I think that's the point when you start to get old. Or maybe by that point you already are.

So what would it take to keep the curious spirit? To keep learning - and to want to keep learning?
