How do you view love? Is it a strong bond or just a positive feeling? Scientifically, it can be caused by the release of chemicals like dopamine, serotonin, oxytocin etc. Do you think chemical reactions would make you give up your life for your friend? What is your take on this topic?
Thanks for all the answer, Even I am not the one who asked the question. 
I just don't know what love really is.
