How to live with three ages

I went to the theater, to see a play with non-professional actors. The male character confesses to his girlfriend that he has a problem, he's 3 different people. A) He's a burning, in-love Don Juan.
B) He's a homosexual, who likes to clean, cook, etc.
C) He's a careful mathematician, tidy, demanding.
The girlfriend looks at him, surprised, «Tell me which one I'm dating».
«Don't worry, all of them, because I am all of them.»
I was left thinking, the same thing happens to me, I have 3 ages and I ask myself which one is the real one. The first one they gave me without consulting me, you see, I go to an office. «Age.» I answer, last century. «I already know that, how old are you now.» The one they registered when I was born, without consulting me. «When were you born.» «Look at the document I handed you, I already told you they didn't respect my rights as a child and right there they registered me.»
She looks at me with a face that says this woman is crazy, finishes writing down the information, before I leave I tell her: «They did consult you about your name», and I leave.
The second age, the one I look like. Ex.: a sourpuss looks at me and says «How old are you.» «The age I look.» He says «You must be close to a hundred.» «You're wrong, I'll give you 105.» Another, kinder one tells me I look 60. I answer: No, I'm thirty-something months old.
Finally, my third age has to do with how I feel.
If there's no humidity and I have no aches I'm 20 years old and I sing, I dance, everything is possible. If instead I wake up aching I feel like I'm 100 and I want nothing, but I've discovered that I have to keep busy, in courses, classes, activities where I force myself to attend and it all passes.
The question arises: which one am I? What do you think?
I AM ALL THREE.
