THERESA MAY - DOES SHE HAVE THE STAMINA FOR THE JOB?

Theresa appears capable as Home Secretary.   When not doing that job she has been in hiding.  We have heard very little of her.  So how would she cope with Cameron's job?  She nodded-off recently in Parliament when Cameron was talking about Chilcot.   I don't blame her.  But does she have the physical stamina to be prime minister?  The wear on Cameron's face and body is testimony to the rigours of his job. His blood pressure must go sky high during prime minister's questions when his face often goes red.  Theresa may have been able to pace herself to do the Home Secretary's job but does she have the physical characteristics that will sustain her as prime minister.
