I find this is a good way of problem solving. Try not think about the problem too deeply. In fact if possible distract yourself. When you brain has had time to do all of the required connections it will present you with an answer. You can then pat yourself on the back for being so original in you solution and not having worried about the answer.
This works about 80% of the time. The other 20% will result in you forgetting that an answer was needed and great stress will ensue when you realised you have let something vital slip.
Please tell me which bar you like the best.
Have an amazing day.
