How do you prepare to live large in "retirement"?

Some friends and I have been starting to think about what it will mean to reach traditional retirement age, to stop working while our husbands plan to work for 6 or 7 more years, or generally to try to prepare for being in our mid-60s and beyond.

We didn't come up with answers yet, but agreed that we want to make sure we are living "larger" lives.  Work and other mid-life obligations have tended to shrink the lives of most people I know unless their work enables otherwise.  Time to change that!

How have you enlarged your life right before or during your retirement years?

What makes you feel like you are living a "large" life?  What holds you back?
