Suffering:

David Pinsof:

"Suffering isn’t a pointless cloud of bad vibes: it’s a mechanism with a function. It evolved by natural selection to help us deal with bad things like injuries, infidelities, and failures. It compels us to avoid making the bad things worse and prevent them from happening again in the future. It’s the opposite of happiness, the “getting colder” signal ...

So a world without suffering would be a world where we aimlessly destroy our bodies and relationships, where we carelessly dig ourselves deeper and deeper into all of our problems, and where we stupidly repeat our mistakes over and over again. That doesn’t sound like a utopia. That sounds bad."
