Yeah, those were the characters I thought of as well. And Muriel is just over a hundred, apparently (born 1890 according to wiki). I guess other than a few notable exceptions, like Marchbanks, most wizards we've seen/heard of still seem to be within the range of normal Muggles, IMO.

I was thinking of Dumbledore at 115 and I just read a story about a man of 100 who still drives himself to work 4 days a week (I forget what his job was now but is was on the physical side for someone of that age). Yes, that's not the norm, but it's clearly not impossible. Oh, and the oldest resident of Purcellville, just up the road from me, turns 107 today.
