I'm not sure 'free-time' is what I'd call it. More like trapped-time.

The time is free. The prisoner is not.

[james_s_tayler]

But you aren't free to do what you want. You are very constrained.

You could do what Nick Yarris did and read thousands of books. I suppose you can let your mind adventure a little. Just seems so ironic calling it free time.

Perhaps 'unallocated' is a better word?

[barbecue_sauce]

That's what free time already means.
