Looking after the elderly is often a thankless job. They don't seem at all grateful for it especially Lord Blackstone who is constantly whining and kvetching if his routines aren't followed to the letter.
Since his stroke, Gordie requires servants to help him with all his rituals. Here is his valet, Mr. Bates, helping him pee.
He also requires a specially-designed feeding station and a cook, Mrs. Patmore, to make sure his dietary needs are met and his pills are dispensed. Still, he is never quite satisfied with his food.
All in the name of duty.
