HELP! -- Swallowing a teaspoon won't paralyse you even if you can't do so (4)

[HenHanna]

Came across this one from a 1960s crossword, and I'd appreciate a
little help with the rationale!
I get the obvious bit, but how does the teaspoon swallowing work?

Yes, there is some evidence that heart attacks are more common on Mondays.

Studies have shown a slight increase, around 13%, in the likelihood of having a heart attack on Mondays compared to other days of the week.

This phenomenon is sometimes called "Blue Monday" [Why are serious heart attacks more likely on a Monday? - BHF].


The reasons behind this are not entirely clear, but some theories suggest it might be linked to ................stress?

hating going back to work ?
