How to experience your childhood again

Take a lemon….cut it into two halves…….on the cut part of the lemon sprinkle salt ……. press the lemon a little bit so that the juice rises up and dissolves the salt …….. now gently lick it with your tongue…… feel the combined salty and lemony sour sensation….. filling up your mouth in a flash……… snazzy and almost electric……….. leading to a sudden deluge of saliva ……..almost dribbling out……and the tongue convulsing gently …… jaws clenching on their own…… and the sensation travelling up to the brain……obliterating every other thought in the brain.
Wow !!!….. Heaven !!…….

In an instant you will be transported back to childhood.

The cheapest time travel one can buy.

P.S.
in place of lemon a tamarind or a tomato also can be used.
