If you were a Japanese.....

If you were a Japanese, when you see this picture, your mouth will be filled with saliva.
This is Japanese traditional pickles "Umeboshi" made of plum. Tastes super sour and salty so that when japanese see this pickles saliva automatically coming out. It's a logic of Pablov's dog. :D
and this is 30years old Umeboshi!!!!!! almost same age as me!
