Well, it did look like he was a bit winded after he went up two flights of marble steps with that f@cking mask on!
I get winded in the grocery store because you can’t breathe through those stupid things.
He looked great - but yeah, when he pulled the mask off he needed to take a few big breaths.
When you do an aerobic activity (like climbing stairs fast) with a mask on, you're rebreathing your own carbon dioxide. No wonder one gets temporarily winded.
