Wendy is writing the first draft of her research paper about symbolism used in George Orwell's Animal Farm. Why should Wendy take short breaks while writing the draft?

If Wendy is writing the first draft of her research paper about symbolism used in George Orwell's Animal Farm, then Wendy should take short breaks while writing the draft. Since it is her first draft, there will be instances that she can't immediately follow on the thought that she has written or will be stuck on particular parts of the draft. Sometimes, revisions are to be made just to make way for an idea or thought that she had recently thought of or has forgotten to write about it. Either way, taking a break makes Wendy feel more relax and thinking isn't hard enough. This makes the oxygen that we take in have their time to be delivered to the brain which allows us to think more clearly. That is why breathing techniques and breaks are very important.
