It’s not exactly one of mankind’s greatest questions, but a frustrated husband believes he has finally solved the argument over whether you should completely remove the foil seal on an opened yogurt.

Pdxchris joked he has been arguing with his wife about the divisive fridge topic for the past decade, but has now claimed victory, sharing the below photo.

He wrote: "A 10 year argument with my wife is finally over."
