What do you consider an adult?
For me personally. I consider an adult to be between the ages of 25-30. Officially developed completely and what not. Maturity wise, I think it definitely depends on the experience of individuals and personality. In my opinion I think maturity is a very general term. There are many aspects of maturity that people are still behind in even going into their 50's and some that people develop faster driving into their teenage years. But if we're speaking on official biological devlopement where to me. Excuses are running out. I would say 25-30.
