How Long Is A "generation"?

[bednobs]

i suppose if i think about it literally it used to be about 20 years, but now more flexible

[aelmpvw]

from the birth of a parent to the birth of their child which is the same as the length of a piece of string

I bag twenty five years,

but ..... my gt grandfather ( four generations ) was born in 1827- first child 1867 which is kinda late for a victorian

I've always thought of it as roughly 30, but apparently it's about 35 for men, 29 for women

I've always thought of it as about 15 years, somewhere between us and our parents.
