Satish and his wife Sarala received a letter from their daughter who had gone to study "Modern Biochemistry" overseas.
She wrote, "My beloved parents, I miss you so much and it breaks my heart to think that by the time I get back, you will be so old.
Therefore, I am enclosing a bottle of a red portion that I have invented. It will make you 5 years younger, and so when I return, you will be the same age as I left you. *Please, take only a drop.*
Goodbye I love you!"
They opened the envelope and found the bottle with the red portion.
Satish looked at his wife and said, "You go first."
Sarala took a drop and when she indeed turned 5 years younger, Satish immediately did the same.
Years later, the daughter returns home to find her mother... She is younger and happier, and she is carrying a baby on her back.
She tells her daughter how the potion worked and how it has made her look younger.
The daughter is happy and she asks about her father.
"Your father? Hmmm! You know how men don't listen! He drank the whole bottle."
"Whaaat! Where is he?"
"Who do you think is on my back?
