I think breast milk might hold the secret to the answer here. When our baby was newborn and breastfeeding, she was healthy and strong and everything, but BARELY ate enough to sustain and grow. She would go 5+ days without pooping with no signs of constipation. The doctor told us “don’t worry about it. Breast milk has all she needs. Nothing more, nothing less”.
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.
