The Undateables

Luke has Tourette's and is reluctant to approach a girl in case he calls her a name, or worse. Richard has Asperger's and will only date a woman living within a five-mile radius, and Penny, whose disorder makes her bones brittle, has never been on a date.

Hadyn has Crouzon syndrome and has undergone 40 facial operations. His twin brother hopes to help him find a girlfriend. Actor and media student Sam has Down syndrome, and Kali, who has William's syndrome, searches for a new boyfriend at a party.

Looking for love can be tricky, but these extraordinary singles entering the dating circuit find it harder than others.
