Althea Briden has come to visit me in the studio.
I have a stroke last May.
So now I am one year old and some weeks, you know, I am new.
And although she might sound it, she is not Italian.
I have no connection with Italy at all.
I am born in Croydon in London, raised in London as well, and my parents are from Jamaica.
In fact, this is what she sounded like just last year.

I'm Ella Hubber, a scientist and science journalist,
and I've been fascinated by Alfia's story since I read about it last year.
Her journey began after she had a stroke.
They discovered I have a blockage.
