I guess, it's a very large topic for me. I would start to explain how anything connect me to life , I can write so many 400 pages books on it. Each activity connect us to the life, but the question is which one connect you more depth. Which one take you to peak of happiness. So I think the topic should be named " One activity that separate you from your life. One Activity that takes your mind away from everything that is connected to the life." When you feel that you don't belong to this world anymore. I think that kind of activity we should discuss. Well now as I mentioned that each activity made by me connect me with life. I want to explain how, and this answer will answer the other question too. In simple words, I am going to answer two of the questions simultaneously. 1- One activity that connect you to the life?. 2- One activity that takes you away from the world and life?.
