Now I know the current castmembers are getting older (not to be insensitive
), but they aren't really playing the part of "old people."
Well...Bob's what, 74? I think that'd qualify.
But I do see what you're getting at. There's another factor to consider. When we think "old people" there's the old stereotype of grumbling Statler and Waldorf-ish people, Grandpa Simpsons and the like, associated with bingo, applesauce and hitched up pants covering artificial hips. In reality, there are quite a few "old people" out there (like Bob!) who are of retirement age, sometimes older, who are very active.
Although death is one of the few truly universal concepts for people, some co-productions of Sesame Street approach it differently than others. Check out the commentary from Jogchem Jalink on "I'll Miss You Mr. Hooper". He's got an entry called "Being Dead Takes So Long".
Check it out.
