Worried patient:"Doctor,I'm very worried.I'm still suffering from exhaustion and fatigue when I come home from work every evening."
Doctor:"Oh,that's nothing to worry about.Just have a few drinks before your dinner---that will soon wake you up."
Patient:"Thanks very much doctor! But when I consulted you before,you told me to cut out drinking alcohol completely."
Doctor:"Yes,so I did.But that was last week,old chap and medical science has progressed enormously since then."
