Yes, I'm old.

I'm old enough to know Daniel Kahneman won the Nobel Prize for his studies in behavioral economics - and how he had changed the lay of the land in the field of economics.  But no, I'm nowhere as old as Kahneman, 

I'm old enough to know there are NO one-size-fits-all solutions when it comes to tax or financial planning. 

I'm old enough to know the Asian expression of how a person falls but manages to grab a handful of dirt.

I'm old enough to know the dirt thrown at @qbteachmt was not exactly grabbed when Bob fell, but the dirt about I'm old was.

I'm old enough to have met a man or two, who always thinks how everybody is stupid, and when a smarter guy walks in the room, he would be bitter inside but could always find an angle to show he's smarter than the smarter guy.

Yes, I'm old, but I'd rather describe myself as seasoned.
