The Secret To A long Life

Everyone asked a 100 year-old man for his health secrets:

The old man said: “I’ll tell you you a secret.

I’ve been married for 75 years.

Promised my wife when we got married that when two people quarrel, the loser has to walk for 5 kilometers.

I’ve been walking 5 kilometers everyday for 75 years!”

Everyone asked again:”But how come your wife’s very healthy as well?”

The old man answered: “I’ll tell you another secret:

she’d been following me to make sure I really finish the 5 kilometers!”
