TASTE

is the best sense.

WHY?

Let me tell you.

1) To taste something, something must TOUCH your tongue.
2) To taste something, your nose must be able to SMELL.

So in order to TASTE something, you must use 2 more senses out of the 5 senses we have. And with 3 of the 5 senses already in action you have 2 senses left. Seeing and hearing. Because you already have the other 3 senses filled in, it is easier to imagine what the thing you are tasting may look like through past experiences; memory. Though it would be more like an old fashion movie. Black and white, with subtitles, because there is no sound. So Tasting something I guess you could say, is like a Old-Fashioned Movie.
