I know I've made this point before, but the solutions to Telegraph puzzles seem to be prone to synchronicity. For example, "Argon" turns up in two crosswords this weekend, but the biscuit musat be taken by the answers to 12 across in this Sunday's cryptic, and 11 across in the next-door GK.
Both clues occupy exactly the same space in the slightly different grid, and the answer to both is ANCHOVY. This phenomenon has been attributed to different compilers thinking alike, but, surely, this is pushing the limits of coincidence too far?
Oh yes, and as for 26 ac in Saturday's GK; Oxygen comprises 65% of the human body? I think not, although it does comprise 65% of the water that does.
