Not this crap again.

Dustin Hoffman was 30 years old in The Graduate (1967). Sean Connery looked like he could’ve been 30 in his high school yearbook photo. There have always been baby-faced actors, and actors who look older than their age. We could just as easily compare Dick van Dyke at age 30 in 1955 with Bill Skarsgård at age 30 in 2021, and reach similar conclusions about the effects of, say, highly-processed food and microplastics.
