P was hit by an automobile driven by D. P brought a federal diversity action against D alleging negligence. P claimed that he suffered serious whiplash in the accident and that he has been physically disabled from working. D's lawyer had doubts about whether P was as severely disabled as he claims. Therefore, D's lawyer served upon P a notice to undergo a physical examination, which stated, "Please present yourself at any time within the next two weeks at the office of Dr. John Smith, who will conduct a physical examination of you to determine the degree of your disability."

Must P comply with this request?
