Significado de "Look like death warmed over"

Seria algo como "parece um morto-vivo", está "com cara de defunto", parecia um defunto, parece "um zumbi", um cadáver ambulante, "um fantasma", etc...

Em decorrência de alguma doença, ou por estar extremamente exausto após fazer um esforça sobre-humano.

Em alguns contextos (em linguagem coloquial) pode-se dizer que "parece bandeira de pirata - só o pano e a caveira" ou "parece que tá só o projeto/parece que tá o pó"/"estar um caco"/"estar acabado"..., etc.

Dizemos "requentar" (warm-over) em inglês, para requentar uma comida, um café, ou para falar de algo "statle" (passado, murcho, duro - como em "pão duro), Então a morte seria algo já frio, esquecido, alguém teria ido buscá-la e a "requentado". Já entendeu a ideia? Algo bem feio, e requentado deve ficar pior, feio de se ver!

Ao ler essas duas mensagens, lembrei-me de quando tive Covid-19 durante a pandemia. Como os sintomas foram fortes, eu costumava dizer que tal doença era a morte "melhorada". Portanto, em inglês, eu posso dizer:

The Covid-19 looks like death warmed over.

It's common the expression to the symptoms or how someone feels, as in:

I'm on day 8 of my second covid experience. I've been testing clear for two days. My symptoms were entirely above the neck. I felt like death warmed over for three days and then turned a corner quickly and currently feel solidly back to normal.

Simon, somehow your account reminded me of a coworker at the office, the guy caught Covid three times, but never had any symptoms! People joked that it was because he was a boozer...no! A heavy boozer!
So, workmates said in jest that it was because alcohol and Covid didn't get along wel, the guy had found the answer before the scientists did.
No one would know that by seeing him, he had a very healthy appeearance, even wanted to work, but tested positive and was sent home for sick leave (in his case it turned out, to the liquor store).

I also learned, on WordReference, that "look like warmed death warmed over" is synonymous with "estar (bem) mal" (from exhaustion or some ailment).

even wanted to work, but tested positive and was sent home for sick leave (in his case it turned out, to the liquor store).

Hahahaha
