" Everyone Asked A 100-Year-Old Man And His 98-Year-Old Wife For Their Health Secrets"
The old man said: "I'll tell you my secret. I've been married for 75 years.
I promised my wife when we got married that when we quarrel, the loser has to walk for 5 kilometres.
So I've been walking 5 kilometres every day for past 75 years!"

Everyone applauded and asked again,
"But how come your wife is very healthy as well?"

The old man answered: "That is another secret.
For 75 years every single day she has been following me to make sure I really walk the full 5 kilometres!"
