I could show to you that i have the ability to drink. If the poision is drinkable you don't have any good reason to believe that i would lack the ability to drink it if i wanted to.
My point is, the only way to prove you have the ability to drink it is by doing it. If you drink it, I argue that you didn't have the ability to not drink it, how will you prove me wrong?
