The 70 year old is likely to be functioning in a different way because of aging. E.g., she or he might be less active, less driven, and even suffer from depression. (E.g., let's say you love to snowboard, but now that you're older you either can't do this at all or ache and are in pain for days afterward, and you just can't keep up like you used to. You're no longer having fun not because you've done this before, but because you've done much better before and your current performance and enjoyment are way below your former expectations.) And this decline might have been going on for decades, so that the 70 year old's perspective here is different not simply because she has been there done that, but because her brain has altered to make her not seek out new experiences, no have great

Really really really bad things happen at aging, e.g. see
and subsequent parts (the tiny hyperlink at the bottom of each part).

Watching old movies and old TV shows, I tend to see people who are relatively young looking worn out and much older. Mayhap many people alive today are aging less slowly already -- albeit not radically enough to live, say, thousand year life spans.

See attitudes of supercentenarials. Ennui and glumness as well as compressed time flux 
is not intrinsic to information acquisition. I'd consider them artifacts of aging, and
reasonably easily fixed (e.g. consider a radically changed outlook during an intensive
psychedelic drug experience).
