The players on CBS' forthcoming Survivor: Panama Exile Island, premiering Feb. 2, include a retired astronaut, a singer, a social worker, a yoga instructor and a babe-a-licious engineer named Misty. The cast of 16 will at first be split into four groups based on age and gender, before being formed into two tribes. The other twist: At least one player each episode will be "exiled" to a remote island, on which Sue Hawk an immunity idol is hidden.
