Law aside, generally speaking, do you consider 18 year old's adults?

It just got me thinking lately. I am 20 years old now, will turn 21 soon, and when I look around me at the current 18 year old's or even compare myself now to when I was when I was 18, I see a huge difference in mentality. When I was 15-16, I thought 18 year old's were so mature and all that, and when I turned 18 I thought I was all grown up and stuff, but now when I look at them, they seem like such children, even though there is not much difference in years.

Also, at what age would you consider someone an adult generally speaking?

Yes
No, adults in my eyes are 21+
