Not exactly. Well, certainly growing up through the years plays a part in it but experiences in Life is what make a person truly Wise. A Kid might witness much lebih in a shorter amount of time than what an Adult possibly could. So, it mostly depends on the occasion anda find yourself in. The Life anda have lead and what do anda make out of everything that has come at you. Being open throughout it and your horizons will expand. Remaining sheltered and enclosed to yourself will not offer anda True Wisdom no matter your age !!!!
Not necessarily; I know adults who still throw tantrums when they hear that they can't get a return without a receipt. But then again maturity and wisdom are two different things.
I think experience comes with age but the wisdom/knowledge that comes with an experience might not necessarily seep into a person's brain. Likewise with maturity.
