A vampire decided to use his immortality to research the best career.
He tried every type of job there was, from innovation to construction to civil service, and he landed on the job of mirror cleaner.
In his book on the subject, he said that the tai chi like motions of the arms were very relaxing, and the mirror will certainly get dirty again leading to job security.
“I’m as surprised as you are,” wrote the vampire. “It was not a job I could see myself doing.”
