Something explained how the "viral load travels from your mouth to other people".

So, I kept thinking of a simple way that will encourage someone to think for themselves with everyday applications.

My usual examples have been:

Cooking and farting.

Make something very fragrant or just delicious for dinner. Invite her to sit nearby and wear her mask. The mask should protect her. If that's the case, she couldn't smell the food.

As for farting, underwear and jeans can't stop that smell from getting out.... ???
