Free Will

I was at a restaurant tonight and saw poutine on the menu and ordered it.

I haven't eaten this in years as:

• it's fattening
• the gravy contains an animal
• cheese forces cows to be pregnant and die early
• I am allergic to milk
• It makes me sick

And yet I still got it.

The theory is the only thing separating humans from animals is free will.

So why is it people so often choose to do the wrong thing?
