It is said that one of the keys to happiness is being grateful for what we have. But we can't always be that way, right?
Is it really our fault that we are not able to be grateful for things we currently have?
We cannot simulate a feeling of a loss, our brains are probably wired to protect us from those thoughts as much as they can. We can try and test this theory, imagine losing something dear to you, try to simulate how it'd make you feel, you probably aren't able to.
Only when we have actually lost something, a consistent supply of good food, for example, is when we'd feel that loss, and what we were not grateful for.
