How old are you?

My heart and parts of my brain have the same age as my bones.
The rest of my body is less than about 7 years old.
People usually give me 32-35.

My bones are alledgedly 41, but since I don't remember the day of my birth, I cannot swear it's the truth.

My soul is that of a 12 years old.

My mind is that of a 20 years old

Sometimes, some of my bones feels like they're 100.
