Crossword addicts

Caught an item in yesterday's Writers Almanac about the first crossword puzzle book.  Published as a collection in 1924 by Simon and Schuster.

At the moment, I do crosswords sporadically which means I never build the muscle you need to tackle the harder ones.  I've been very irritated by the Guardian Review setter recently because they seem to be addicted to geography clues. 

Perhaps I'm saving up the activity for later in life when I have fewer physical activities.
