If I eat a ton of garlic, and you eat a ton of garlic, can one of us recognize the smell of the other?

I don't think either of you will be able to smell each other because eating 2000 lbs of garlic will surely kill you.

yes because everyone's internal microbiome causes differing smell profiles

Even twins will have slight divergences due to the difference in the occupancy of time and space

My wife and I looooove garlic. We can still smell it on each other.

At university, I had a housemate who was doing research into the chemical(s) in garlic that give it its smell. She was completely nose blind to it. You also went nose blind to garlic, just by being in the same house.

Oui

Rationally I know you will smell one another but I still maintain the opinion it will cancel each other out as a joke - to great frustration of my wife

you smell different, but you still smell unique.

So... we're going to Italy?? PIZZA!!!!!!

No, it would be the same if I ate your ton of garlic and you ate my ton, by then neither of us would have a sense of smell either way.

So the universe remains in balance, as it always has.

This seems entirely testable

Years ago, my friends hosted a garlic-themed dinner. I rode a motorcycle there, and it was raining on my way home.

For the rest of my life, I will remember having to choose between opening the face shield and blinding myself, or closing the face shield and choking myself on garlic fumes.

My guess is that 2 mutually garlicked people will be able to smell each other.

Find someone to do an experiment with.
