Meet the cosmonauts

Cheryl is a lively, ambitious and opinionated girl who loves people. She is also impatient and hates being alone. A firm believer in fate, she believes in reincarnation and ghosts - she says a guardian angel visited her when she was aged sixteen. She fears drowning and fire but feels that taking part in a 'thrill-seekers' show will give her the chance to do something unique.

Cheryl describes herself as a typical, up-for-it 23 year old girl. She hates liars and smoking, and enjoys clubbing with her friends, clothes and relaxing in a bath with a glass of wine.
