Ninety-year-old student: 'Education will be your wealth'
Priscilla Sitienei has enrolled in primary school for the first time in her life - at the age of 90.
Her head teacher in Kenya's Rift Valley believes she is the oldest pupil in the world.
The former midwife is determined to learn how to read and write and attends every class, including, dance, English and PE in the same uniform as the rest of her classmates.
The BBC's Ed Thomas spent a day at the school to find out what drives her passion to learn.
