I recently recorded a three-minute video chat with my friends Jan and lan over coffee, which kind-of blew up on Facebook and as a result (and after plenty of encouragement from TYP listeners), I thought we'd get the youngsters back on the show, five years after their podcast debut. At 84 and 86 years-young, my guess is that their biological ages are both somewhere in the vicinity of twenty to thirty years younger than what the calendar says. I truly love them and I expect you might too.
