There are a couple of old men on my street who have made it past 90. Shaky Jake, as I call him, is 91, except that there is nothing shaky about him. I encountered him the other day on the rocky trails of the Superstition foothills, upright, lucid, happy.
Across the street from Jake lives Tim, still self-reliant and sharp at 95.
From my conversations with them, the quality of their lives is good. But attitude is everything, here as elsewhere.
