William Gladstone (former PM of Great Britain, 3 times between 1868 and 1894) said:
'If you are cold, tea will warm you. If you are too heated, it will cool you. If you are depressed, it will cheer you. If you are excited it will calm you.'
He had no comment on coffee.
Isn't it time to put the kettle on?
(This picture of course is not Gladstone but someone else who is far too perky for his own good)
