Sleep-tracking apps log every toss, turn and REM cycle, on the principle that nothing improves until it has been measured.
Bring the classic method up to standard. At 11 p.m., open a spreadsheet and log one sheep per row — breed, fluffiness out of ten, fence clearance in centimetres — with anything under 30cm highlighted red. Field notes: 1,412 sheep catalogued on night one. Sleep arrived at 04:10, face down on the keyboard, and row 1,413 reads zzzzzzzzzzzz all the way to column AZ.
