Before heading outside to do some yard-work, it's time for a quick thought-experiment. Here goes: if i didn't believe the Lord Jesus,

then all i would be is a hasbeen (that never really was, to begin with ;) a hag, an old harpy.  Hey, i am in my early 60s, and look more like early 70s, so i qualify in describing old age.  If i didn't believe in the Lord's Word (Holy Bible) then, yeah, i'd be grasping at pitiful, delusional pat little phrases like "sizzling toward..."  (gag me with a ladle) and basically fighting the always and inevitably unsuccessful, ever time-consuming battle against the natural process of aging (a fact of life in this fallen world).

In a world where the Lord does not exist, and where evolution rules, uhm, old people are nuthin but redundant - unless you're very rich, but most people, like some 95% are not super-rich.   Once the next generation, reaches adulthood, in an evolutionary civilization, the over 50 crowd has basically outlived their usefulness, and become a resource pit.  Yeah, "useless eaters."  That's evolution baby, that's where evolution goes.
