I'm taping Headline Saturday tomorrow, which airs on WRAL 7 p.m. Saturday. The show will be on the issues surrounding the growth in the elderly population, and how we're going to meet the needs of a rapidly increasing group of seniors.  If any of you have any questions you'd like me to ask, email me at dbarkin@newsobserver.com.  The show tapes at 9:30 a.m., and I'll check my email beforehand.
