Angelina it was one of the first things i learned in economics class at school and it is one of the first things every economics student learns. i only know it from the economic context.
Well,even if not the main subject for it,I guess it can be useful to know it in these studies.
Angelina that's interesting, i would have argued with me about the third level, but i don't agree at all about the first level. 😂
You would put "sexuality" in the third level?
In my opinion,third level is "relationship",and "one night stand" or masturbation would be in the first level,for example.
