Youth is ....
Youth is not about age its only about your pure feel.perhaps you know somone who is under 40 years old but he/she feel like old people,dress like them and in some country they always say I am not young enough to do this or that.
I suggest you to dont think about your age and number of candel on the birthday cack,just think about your target,your happines and just try to enjoy every secounds of your life becouse its not renewble.
