What is nessesary?

What help you to live vigorously? I think it depends individual. As for me, it is orange and banana. I have made it a rule to eat 1 orange and 1 banana everyday since I was junior high school student. As most of my friends know that I am really care about my health, I think it's because of my father. He really cares about his and his family's health. I guess my family will live more than 100 old. Also I want to my parent's live as long as they can.

Anyway, If you feel fatigue you should eat orange, it contains citric acid which release you from tiredness. Also orange contains vitaminC which make your cells recover and you can feel good.
