I think a lot of people won't admit to regularly putting up their feet as (a) from their childhood they were taught that this was lazy (so they still retain some feelings of guilt over it) and/or (b) they don't want friends to think their lives are empty! BUT I saw my mother never rest (even when she was ill she fretted over things not getting washed/tidied, etc) and she died too early. I've seen my best friend burn out and is now in a wheelchair (and still raging because "I can't simply do nothing") - as though resting your body to enable it to relax is "nothing". My favourite poem is WH Davies' poem "Leisure" - says it all really:
What is this life if, full of care,
We have no time to stand and stare.
No time to stand beneath the boughs
And stare as long as sheep or cows.
No time to see, when woods we pass,
Where squirrels hide their nuts in grass.
No time to see, in broad daylight,
Streams full of stars, like skies at night.
No time to turn at Beauty's glance,
And watch her feet, how they can dance.
No time to wait till her mouth can
Enrich that smile her eyes began.
A poor life this if, full of care,
We have no time to stand and stare.
