Pedigree Query

Pine Bluff and Silver Ghost are pensioned now. It was mentioned in the announcement of AP Indy's fee remaining at 300K. Can we assume Pine Bluff is showing his age early and/or losing fertility? He'll be 18 next year. Silver Ghost will be 25 so I can see that.

I guess some studs can't exactly go the distance...in other words, still be as fertile as they were at 12 at 22 and beyond.
