partly because I've been into bodybuilding for 25+ years and I'm a mortician
that I find myself critiquing physiques no matter the age
the mortician side of me sees bodies at the end and also the family trees of the deceased
I dont think it's "sick" to mentally extrapolate what you think a youngster will grow up/into
I've done it at kids pee wee football games
seeing the 9 year old star of the team and think what he'll be like at 13-15
for females I do find myself thinking how she'll turn out
but there's no sexual feelings about it
you can see this korean girl will blossum into a very fine proportionally almost perfect young lady
