The secret life of twins

With more twins being born than ever before, a new one-off documentary explores the extraordinary stories of several sets of identical twins.

Eighty-one-year-old Peter and Paul Kingston still live together despite both being married and, having chosen the same career, they are also the UK's oldest DJs.

Tim and James Brown's bond became even stronger when James saved Tim's life in 2012 by donating a kidney. Both sets of twins join us today.
