I am a very busy physician who is fully booked on clinic days. My last patient is booked at 4:45 p.m. and I rarely leave after 5:30 p.m. I leave with all my charting done.
Mr. X. has a sore throat. He buys some penicillin and gives himself, not enough to kill the streptococci (bacteria known to cause sore throats and tonsils) but enough to educate them to resist penicillin. He then infects his wife.
