https://medium.com/neodotlife/onno-faber-part-4-15ae0cd08db6 > Onno Faber, a 36-year-old tech entrepreneur, stands straight up in the center of a modest living room, his shoeless feet planted in the gray striped rug. He looks trustingly at the music teacher who faces him, flashing her his frequent, accepting smile. Then he takes a breath, lifts his clear tenor voice, and sings. > Tomorrow, Onno will be video conferencing with parents of children who have rare diseases, to pitch them on his new tech platform to propel unconventional medical research. Today, he is far away from all that, as his voice reverberates through this little San Francisco room, lifting it up and away from the desperate streets of the Tenderloin neighborhood below. The notes vibrate in his wavy blond hair and green eyes, and in the tumor that’s growing quickly on his right hearing nerve — the only hearing nerve he has left. Onno is hearing the sound fill his body while he still can, before neurofibromatosis takes the other nerve away.
