Yes! Afternoon naps! I used to feel so guilty about nodding off mid-afternoon. I'd say "Er... very late night last night..." Which was a pack of lies, as I've always gone to bed early. Now I do not care. I go to bed at 3pm, undress and get under the duvet (no dozing in a chair for me!) and sleep blissfully for at least an hour. I wake up very refreshed and ready for the evening. When you're getting on a bit, you care less and less what people think. You realise it just doesn't matter.
