¿What does one put in a Bio?

Do I put that my favorite color is black?
Maybe how my hair goes past my back?
Or, I want my hair to be blue,
And I wear size 8 shoe.

I have a cat named Tangelo,
I also know how to sew.
I absolutely love art,
and I have a quite big heart.

I love to read and write.
I think sunsets and sunrises are a sight.
My favorite number is sixteen,
and to my family I'm a drama queen.

Love is a silly thing,
but I do want a wedding ring.
I love tacos,
I've got all ten fingers and toes.

That's all I can think of for now,
Don't be a cow!

(I don't even know what that means.)
