Taste. The middle, forgotten brother in the family of senses.
They don't have helper dogs or monkeys for people who can't taste anything. No one is working on smaller and smaller devices to amplify or stimulate tastebuds.
You can either taste or not and no one really cares.
The one good thing about not tasting anything is you can win all kinds of money on the playground by eating things. Things that might seem disgusting.
