Laziness

We have a duty lethargy to spurn
And to stir ourselves up to good deeds in turn

Tiredness

If tiredness comes, then you must fight.
It will pass; just sit tight.
A nap's okay, if you feel dead,
Just don't go back to bed.

(Tiredness during the day is not the problem it once was for me but I still think this is good advice).

Lie down there and I'll fan you

One of my mother's this. It's ironic, of course, a response to laziness, though sometimes I would lie down and once she even did fan me! Apparently it is an RAF saying from the twenties, influenced perhaps by the existence of Raj punkah wallahs.

Lie down there and I'll fan you
(or Lay down there and I'll fan you).
