Anyone else have pre-determined ages for townies in their heads?

Some examples:

-Bella Goth is 43, and Mortimer is 48

-Nancy Landgraab is 52, and Geoffrey is 49

-Bob and Eliza Pancakes are both 36, Bob is older by three months

-Johnny Zest is 28

-Agnes Crumplebottom is 81

-Vivian Lewis is 67

-Don Lothario is 33

-The Caliente Sisters are 28, and Katrina is 46

-The Pleasant sisters are 25

I have plenty others if anyone wants to hear, just ask 🤣 but does anyone else do this?
