You can. An experiment, pick a task you don't feel like doing, and try to do the actions required, for the sake of the experiment (not for the sake of the outcome of the task itself). Obviously, you can make your body do whatever you want.

Now, you might counter this argument by saying you were only able to do it because you "felt" like doing the experiment.

Here, we must acknowledge a distinction between wanting to do something and feeling like doing something. And a further distinction between different reasons for wanting, and the ways you think about those reasons (logical steps, assumptions, context).
