An Indian man of 100 has gone back to university, saying you are never too old to learn.

Bholaram Das had his birthday last week - and to mark the occasion enrolled on a PhD course in north-east Assam state.

"If my son can get a PhD at the age of 55, why can't I do it at 100?" said Mr Das, possibly India's oldest student.

He was imprisoned for opposing British rule in 1930 and went on to work as a teacher, lawyer and judge in Assam before retiring in 1971.
