The woman who is believed to be oldest person alive celebrated her 128th birthday this week.

Johanna Mazibuko, of South Africa, has identity papers which she says she was born in 1894.

She says a combination of fresh milk and wild spinach has helped her live through British colonialism, apartheid and two world wars.

Mazibuko had seven kids with her husband, two of whom are alive today. She also boasts some 50 grandkids and great-grandkids.
