Saging on screen

I watched Boston Legal for the first time the other night. I found it realistic and psychologically astute. I had especially tuned in to watch Candace Bergen who has grown with her age beautifully. She has always portrayed characters her own age and done them great justice - in this case literally! What actors or actresses do you admire for demonstrating saging and embracing who they have become with each passing year? What shows do you recommend I check out that also focus on saging, rather than stereotyping those over 50? I welcome your suggestions!
