Good advice?

@rondetto Said

A tough building site labourer once counseled his grandson that if he wanted to live a long life, the secret was to sprinkle a little gunpowder on his porridge every morning.

The grandson did this religiously and he lived to the age of 93.

When he died, he left 14 children, 28 grandchildren, 35 great grandchildren and a fifteen foot hole in the wall of the crematorium.
