Man went to the doctor.

"Doctor, is there ANYTHING I can do to live to be a hundred and twenty?"

After considering it the doctor replied, "Yes. Go way, way back in the hills and marry a widow with twelve young children. Buy a farm where the soil is mostly rocks and a broken down, spavined old mule to plow the ground with. Walk everywhere. Grow your own food from the farm. After you do that, give any money and possessions you have left over from your previous life to charity."

"Good Lord! How will that make me live to be a hundred and twenty?"

"It won't, but it will make the next five years seem like it."
