I wonder, is your happiness the same as mine?
I know that you weren’t speaking to me but how could it be? You’re a violent chaotic anarchist 
which may mean that our essences are different.
But it’s possible that some of the things which bring happiness to you, which cause you to become happy in the moment, may be the same for me - and for others. I did say possible but maybe I need to whittle that down a bit and say “plausible”.
You enjoy watching women mud wrestle – slopping around in the mud and I enjoy watching men surfing, running, especially if they have awesome physiques. Maybe not much different there, just different appearances. hahaha
Neurons and brain chemistry also account for the qualia of our happiness. You might be surprised to know just how enjoyable it is for me when I watch two squirrels scampering up a tree.
