Hear it from people who have fallen in love before.
I asked some friends and family to describe what falling in love feels like in one sentence. Here are their responses.
"Falling in love is like looking at the world with rose tinted glasses, everything is softer and beautifully illuminated."
Alana, Age 24

"You do things together that you would not normally like to do, but because you're together you enjoy it."
Lauren, Age 22
In long distance relationship for 3 1/2 years, in total 5 years with boyfriend Osiris.
"Makes you sick to your stomach at first."
Annette, Age 50

"Falling in love is the feeling of a magnetic attraction to a woman you want to be with forever."
Mike, Age 50

"When you fall in love it feels like a 24 hour high when the only thing you think about is that person. When you leave them you're not yourself and not completely happy, because they complete you."

"Falling in love feels like an internal hug."
