One thing that everybody does, loves. Love is just like a Tryptophan.
They didn’t produce in our body, we got it from other. They give us some relax when we need it. But they could became so poisonous when we got wrong. And could be so dangerous for our live if we didn’t handle it well.
They aren’t toys anymore, they are working in our neurosurgeons, so they are aliveness. They make us feeling comfort and then so sleepy when we together with them. But they could find us unwell when we lost them.
I said it just like a “Lovetophan”, absolutely love is tryptophan.
