THERE is nothing like boiling an egg to stir up emotions. 
Only the other day I was at loggerheads with my dad, who dismissed my four-minute rule as too short a time, saying five-and-a-half is best. He seemed surprised that the egg I presented to him was acceptable. “It’s alright,” he reluctantly conceded. My husband agrees with my timing, but says my toast is “like charcoal” and is in for far too long.
Now scientists have given a definitive answer to both egg and toast. They say four minutes 15 seconds is the ideal amount of time to boil your egg, while white bread should be toasted for precisely two minutes 55 seconds. Well, now we know. 
I wonder how much they got paid to come to that conclusion.
