You know what's better than free will? The illusion of free will. Some would argue that people don't actually want to be free. They wouldn't know what to do with themselves if they were truly free. Everyone would go crazy and die meaningless lives. I think it's the Illuminati who argues that. I don't remember though. It's been a while since I've been to an Illuminati meeting. I still use my discount card though. Illuminati members get 10% off their Starbucks purchase. It doesn't seem like a lot but it adds up.
Why do I bring up the illusion of free will? Because that's exactly what this picture depicts. Sometimes just the feeling that you can control something, like the temperature, is enough to make you feel good. You don't actually need the temperature changed. The mind is a powerful tool.
