This is a scientist video which prove to give an cientifical reason to our love feelings. I don't agree with this video, because it sais that the love comes produced by ficical things like the colour of the hair of the other person. But i do not think that love can be determinated by a colour, or by the physical conditions tht have a person. Ths video also sais that the love is probably an a quimical effect tht makes our brain, it sais that the love is the same or attraction, and the love is not the same of attraction, attraction it's just a part of the love, and not the same. I think that try to explain the love with a scientific mentality have not sense and is a waste of time. I will sai one think to the scientists: leave this issue for shakepeare and antother writers which really understand  the love.
