a. Discuss the validity of your friendâ€™s statement, providing evidence in support of or refuting his claim.
b. After further conversation, your friend tells you that he stopped taking his initial antibiotics after 2 days because he â€œfelt 100% better.â€ Explain how this action might have played a role in the redevelopment of his infection.
