How do you personally define the word "love"? where do you feel this definition developed from?

I would personally define love as an unconditional sense of caring for someone else, even when things are tough and supporting them in whatever they want to do in their life. I think love is that sense of knowing that someone has your back even when you feel alone and you are in your dark places. I think this definition developed from my past experiences because at times when i felt i had no one there was always that one person who helped me through whatever i was going through 

Ok, before buying a burger. think of you diet and calories. how many calories are you suppose to eat a day. and look at how much fat, calories, salt is in it. if it is ok to you, then buy it. but if you think that it's to much fat and salt for you. don't buy !
