As a democratic socialist I can see how it would be wise to apply TERM LIMITS to all vocations professional or just skilled. The DIVISION OF LABOR is a necessary evil in capitalist society - inconceivable without it. But so much JOY goes out of LIFE by dogged devotion to ONE job for decades until one reaches the age of HAPPY RETIREMENT BLISS . Even the Catholic Popes are getting wiser here. When I was very young - and a budding New Age Beatnik- I was inspired by British philosopher Bertrand Russell's witty essay " In Praise of Idleness " . Russell admitted that it was a just a nasty habit ( and fear of starvation ) that kept him working hard to an advanced old age ( which he spent excoriating American imperialism, Senator Whitehouse ) . I at least had the good sense to retire from whatever " employment " at the age of 62 .
