A woman was visiting her elderly parents and in conversation with her mother, she was surprised to learn that her parents, both in their late 80's still made love.
Worrying that the exertion of having sex might cause them to be over stressed and die, the daughter expressed her concern. Her mother reassured her that it was quite safe, explaining that they timed the tempo of their love making to match the ringing of the church tower bells.
Some months later, her father passed away. The daughter asked her mother 'what happened?'. Her Mom replied--"Well, dear--we we're making love and his darling heart just gave out".
The daughter replied---"Mom--I thought you said you had a safe method, going with the timing of the bells.."
Her mom replied--"Yes dear, and all would have been fine, were it not for that damn ice cream truck..."
