Thinking, thinking, let me tell you what I've thought.
Fishermen enjoy fishes but doctors and children also do, so it can't be the right answer. Then I thought what other things fishermen use to catch the fishes? They use a bite. What bite? Worms. Then I remembered how much we've loved to play with worms as children. Doctors hate it, we know why. So my answer is worms.
P.s. Apples hate them too!
