I guess I'll be the one to ask this....

How did chief use the bathroom?
What did the chief eat?

I highly doubt his augmentation made it so he didn’t have to eat, sleep, use the bathroom or shower…

I feel like you already know the answer to this question.

I have theories, but the implications…

The MJOLNIR Armor is self-sustaining. He doesn’t need to do those things.

Recycling to a whole new level… is all i have to say about that topic.

This. Something along the lines of nourishing futuristic soy paste, or some kind of protein IV. And urine or whatever is more than likely just mega-filtered and reused for the former and hydration etc.

Use your imagination, whatever seems the most logical, probably is.

Magic

The armor recycles waste for reconsumption.

even though he feels aparted when the armor is not on, he can still take it off.

He has been ordered to see people without his armor on before.
