He had this para-normal ability about eating and food. He would always know what he was going to eat, days in advance.
He could taste it.
He could feel it go down (or coming up).
Then, one day, it all stopped.
So he killed himself, to avoid starving to death.
He had a very special psychic ability: whatever he would paint would never, ever come to pass.
Even though he would paint what looked like very realistic and believable scenes, the event depicted would never occur.
Unfortunately, he never knew he had this power. Nobody else knew, for that matter.
