I just invented something, so I thought I'd let it fly free and give it to a grateful world. You lucky people are the first to hear about it. How about a Covid mask that has an inflatable red tongue attached to it, that when deflated sits unseen in a slot in the mask behind your mouth. When you exhale, the force of your breath inflates the tongue and drives it out through the slot in the mask. When you inhale, the external air pressure forces the tongue to deflate and draws it back into the slot, where it is hidden. With each cycle of your breath, the tongue pokes out and in, out and in, out and in. Imagine what a hit this would be in supermarkets and fashionable clothing botiques. Narcissists, rejoice, I am your salvation.
