A 'threading' in time saves nine

Bored sitting inside his parked car, waiting for his wife to return from a beauty parlor, the husband, a physician walked to a nearby lab and ran a routine blood test. Just to kill time. 

The result was abnormal and subsequently he diagnosed an early cancer getting ready in him. Caught it right in the budding stage and killed it.

So the next time your wife wants to go to the parlour, don't say no.
