Sounds like a good plan to me. 

Listen to what Stefan Sagmeister has to say about the power of time off and think about how you'd pull this off.  This is about taking a few less years of retirement and living a little more during your working years.

Thanks to the folks from the TED conference for sharing this and for Stefan for making us think about it.  This event is definitely on my list to work my way into at some point.
