If tension is related with the 'brain' activities, why do it leads to 'heart' attack? AND and if?

I find many misunderstandings in your question. Firstly- tension may originate from thought, but ultimately our brain and various parts of our body are linked by nerves- so one effects the other...

Another thing is that love does not originate in the heart----maybe you could say that the heart beats faster or aches when you think of someone you love----but that does not mean that love originates in the heart.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
