Ions. Lots of them. travels through them neurons, creating the illusion of ecstasy, pleasure, pain, and the ultimate orgasm. Ultimately, you can feel good even when someone close to you die. Just that, the ions have to go in a different way to some other place in your funny brain. And you can feel bad for no reason, you can laugh when you are homeless. Just, re route the ions!!
Well, then, it would be possible to do nothing and feel good, you can feel good when lonely, you cannot feel the pain when you starve, and you dont need someone to love you.
I just need to rip open the brain, re wire the neuron mesh, and feel good doing nothing.
And when someone feels happy without doing noting, we stamp them lunatic, and treat them.
