Hey, everyone, do you know that love has a lifespan of three years?
when you're in love and your heart suddenly starts beating faster, it's really because there's a narcotic being released inside your chest. But after two or three years, once you've gotten used to your partner, it won't be released anymore.
so basically, the lifespan of love lasts for about three years.
