The apple

In England, they say, "An apple a day keeps the doctor away." In Japan, the same saying is "the plum."
Which fruit is right for each individual is a matter of personal belief. Personally, I stick with the "apple."

 According to the Bible, the apple is already the fruit in Christian tradition that can do more than just open our eyes. 

For example, New York City is nicknamed the "Big Apple." The Beatles' record label: Apple.

Today, the saying is still recognised, but the meaning is the other way around. If you see a doctor too often, the apples stay away. All they can do is subscribe to some pills.
