Don't believe me?
Take a piece of paper towel and dry the center of your tongue. Now take a small amount of sugar and place it on the center of your tongue where you dried it.
Can you taste anything?
Now close your mouth. The moment the saliva hits your tongue the sweetness will come back.
This is part of the reason if you suffer from dry mouth that you will find food less appetizing. If you do, try taking little sips of water while you eat. It may help.
Happy random fact Friday! And Happy long weekend!.
