Spain until the late 60's (because the dictatorship put Spain cultural and economically behind the rest of Europe. My rural parents began to help parents in their village even at age 4 doing small tasks. No wonder the age on consent in Spain until a decade and a half ago was as low as 14... because it was a unchanged byproduct from the 70's/ society, where by age 14 the 99% of the population couldn't affort anything but basic education (which lasted into that age) and for sure by 14 you woud already be working in a trade as an apprentice as every other adult. And, OFC, you would have aches in your back because of farming with your parents (and women helped at home too).
So a 14 year old in the 1960 could one-hit KO a current 18yo kid from today in the spot because they had drastic hormonal and physical changes due to the hard work. OFC when they hit 30 they almost looked like 50 yo's from today.
I always laugh at some old soccer trading cards from the 80's where tons of players being at 19 look like men in their 40's. Yes, tons of them smoked like chimeneys and drank like pirates.
