"When Elvis Presley died in 1977 there were 200 Elvis tribute bands. In 2007
there are approximately 200,000. If this trend continues, by the year 2060 one
person in four will be an Elvis impersonator."
Mentioning this to my son, a college freshmen, he said that a recent aptitude test he took actually included "Elvis impersonator" as one of the career possibilities.
Some days I can hardly wait for the future. (Until I remember that I'll be really old then.)
