Private Proofreader

My son is going to college to be a pharmacist, and he regularly e-mails me his papers to proofread. The last paper he sent was almost perfect, except for a small paragraph he had written about something he called “ubiquinol coq10“. He wrote as if it was one nutrient, and since I am taking a coq10 supplement, I highlighted that section and wrote that he needed to clarify that it was two different nutrients. After he had re-written his paper, he called me and said thanks for catching his mistake. He admitted that he hadn’t even researched the nutrient, and said he would have been pretty embarrassed if his professor had caught it.
