Being a vegetarian for many years I have been asked by different people about the reason behind it many many times. My answers have been varied depending on who was asking and the situation. From a serious answer to a not serious one.
Not long ago I was in a tour group with new people for almost 10 days. Very often we sat on same table during our breakfast, lunch or dinner. And we talked. During this eating time ussually someone would ask me what I was eating on this diet. Usually different person because we sat randomly. And I gave a different answer too.
I remembered when someone asked me the same question, I replied “I want to live a thousand years.” It was a apontaneous answer, of course Everybody who was there laughing at me. To become a vegetarian means to take a lot of vegetable and fruits for daily intake. Fruits and vegetables are considered to be healthy food, containing high vibre, fresh, easy to be digested etc etc. If you are healthy then you are more likely having a long life span. Well, that is the simple logic.

He then said that if I live that long, I would be lonely because probably all my friends would have died.
But then someone said “Don’t worry, I will travel with you. I will become your travel buddy.”
Have you ever thought of having a long life span? What are you going to do with your life if you are given a long life span? Will you be feeling lonely?
If you have something to contribute to humanity or to people around you, you will experience your life so valuable. Your heart will be full and you won’t feel lonely. To feel lonely is to feel lacking of something in the heart. It is feel a bit empty in your heart. A lonely heart is an empty heart. It is by giving that your heart will become full.
Think of what you can contribute to people around you instead of what you can take from them. Be where you experience yourself having enough for yourself and for giving it to others, not be where you need to take.
