Fall in "LOVE" what! really???

Friends , from birth to death we all are fall in love of any thing, anytime and anywhere .
Not only with humans but also for animal, living non-living things ..

sometimes we fall in love just because of we like her/his hair ,lips,eyes,body something more which i am not able to mention here..lol

the point is; is this enough to fall in love with somebody or we should first have to know her//him?

I think everybody is having different opinion tell me what do you think about fall in love?
