After a childhood in the 1960s, Leary went to Emerson College in Boston, where he tried his hand at acting and writing.
Now, earlier in the biography, we were informed that Leary was born in 1957, which pretty much gives us all the information we need to figure out that he had a childhood in the 1960s. It really doesn't need to be further commented upon. The placement of an adjective -- any adjective -- before "childhood" would have helped this clause avoid complete pointlessness: "impoverished", "happy", "robot-afflicted". But instead, all we learn is that Denis Leary, in common with every other human being on the planet born in the late '50s who did not subsequently die before their fifth birthday, had a childhood in the 1960s.
Well-played, IMDB mini-biographer Jack Witzig. Well-played.
