J.F. Sebastian

J. F. Sebastian was a genetic designer employed at the Tyrell Corporation who suffered from Methuselah Syndrome, meaning his glands "grow old too fast," thus leading to accelerated aging and an early death. His condition caused him to fail the medical examination to leave Earth for the Off-world colonies. By November 2019, J.F. lived by himself in the Bradbury Apartments, given to him by Eldon Tyrell.
