What does Seneca love the most? Things with are interactive. For example, lights. Having the ability to turn the light on and off is what he loves the most. Action and reaction.

Perhaps even for us adults, the best is things which allow interactability. Rather than passive consumption.

This is where lifting weights, and powerlifting is so interesting; the privilege of interacting with a very very heavy weight is what engages me the most!

Interactive media is the future.

Perhaps this is where shabu shabu, and Korean barbecue is so interesting; maybe people do like cooking their own food!

Perhaps this is why touchscreens are so addictive; we touch the screen, and something happens. We love this!

This is also where physics is so great; physics is an ultimate opportunity to interact with gravity, and the embodied world.
