Do you think children are developing faster now than they did 20 years ago?

I don’t know if it is makeup, clothes, diet, or what, but when you look at school pictures of my brothers and my classes in elementary school and middle school, the kids did not look as developed as they do now. Mostly the girls. Was is just a simpler time? Is it just makeup and hair, or is there really a difference in how fast kids physically mature now? 16 year old now look like 20 year old when I was young I swear.
