Deanna Troi was born on March 29, 2336 (according to Memory Alpha, so it was established from one canon source). Then again this would be NuTrek so that'd go out the airlock--they'd probably make her three-breasted as well
Seems odd to me that a fully-licensed, multi-species, practicing therapist would only be 28 years old. Which would be Troi's age in "Encounter at Farpoint" if you use the 2336 date.
Troi was originally suppose to have three-breasts. So what's the problem?
