For those folk who enjoy the 'sauce' from time to time there is an infallible test as to whether you
should leave the car and hand over the keys.
It is a free test as to your inebriation and is said to be the toughest tongue twister in the English language:-
''The sixth sick shiek's sixth sheep's sick.''
So if you start seeing purple 'Lennies"- give it a roll.
