And For Whom the Bell Tolls is a novel, just like The Valley of the Dolls.
Mice have an average life span of around 2 years, he’s doing amazing compared to Bart.
I think that if you spot each episode a generous 3 days in average length (some longer, some shorter), you would get right around 5 years for the run, so far. Which fails to account for the children not aging, but at least they would not be in their 30s.
