Once an honest man went to a Doctor for his cardiac
problems, The Doctor Thoroughly examined him and gave
him some pills and also asked him no to use stairs.
After few days he came back to him for re-check.
He asked the Doctor, " Doc, Can I now use Stairs?"
The Doctor replied, " Sure you can...Why not?"
The man breated in relief and said, "Thank God, at least
now I don't have to climb the pipe line".
