You have a point and it's a good one. For my peeps though, I'm not certain it's true. For one thing, Alex and Walter always have each other. And although their children will die eventually -- I'm sure they have much longer than normal life-spans thanks to their parentage -- they will also have their grandchildren and whatever adventures they find themselves caught up in to to keep them going. Peach addressed this in one of her series; Walter starts to feel tired but refuses to give up as long as Alex wants to continue his search for Mulder and/or Mulder's offspring.

I suppose it helps that one of the grandmothers in my family (my mom's first husband's mother) is 99 years of age and at her last birthday party revealed that she's started feeling old. I can't quite imagine it -- I'm 48 and I feel old. She has 51 years on me and appears to be in great health and spirits. For sure she has a happy personality and it isn't as if she hasn't lost friends, her husband, and even some of her children during her lifetime.
