It is a deeply-held assumption that every person is either male or female, but many people are now questioning whether this belief is correct. This compelling and sensitive film unlocks the stories of people born neither entirely male nor female. Conditions like these have been known as 'intersex' and shrouded in unnecessary shame and secrecy for decades. It is estimated that DSDs (Disorders of Sexual Development) are, in fact, as common as twins or red hair - nearly one in 50 of us. The programme features powerful insights from people living with these conditions, and the medical teams at the forefront of the field, including clinical psychologist Tiger Devore, whose own sex when born was ambiguous.

Roses are red, violets are blue but according to the latest understanding these colours are really an illusion. One that you create yourself. Horizon reveals a surprising truth about how we all see the world. You may think a rose is red, the sky is blue and the grass is green, but it now seems that the colours you see may not always be the same as the colours I see. Your age, sex and even mood can affect how you experience colours. Scientists have unlocked the hidden power that colours can have over your life - how red can make you a winner, how blue makes time speed up. Watch an experiment where for people in a blue pod, a minute lasts 11 seconds shorter.
Raging Teens follows a group of young boys and girls throughout their teenage years and captures the changes that the body undergoes through puberty. Its main focus, however, is on Beatrice and the changes she undergoes such as shopping, growing breasts, pubic hairs and her first period (her mother bought her some Chocolate Éclairs to help celebrate which must be a British thing). The boy's side covers testosterone and what changes it spurs in a lad's body such as facial hair, their voice cracking at the wrong time, and parts of the body that have until now lain dormant. You also learn that a pubic hair only grows for 6 months, which keeps it short, and is actually flat oval and not round which is why they curl.
