Age is a state of mind...

At 85 my grandfather could still dead lift and carry 500 pounds.

He told me that his neighbour was about his age and single handedly carried the flywheel off a combine when his sons (a couple of massive guys) were unable to budge the 800 pound part.

My step father could dead lift and toss a full oil drum when he was in his mid fifties... they weigh about 450 pounds.
