Our foreman made us do five minutes of hamstring stretches last year, and it totally changed the game for my lower back. I still do that routine before every job now.

Baker Street station always has someone reading on the benches. I saw a guy with a Pratchett book last Tuesday and asked which one. Turned out he worked in the same office block as my dentist. We ended up talking about adaptations for twenty minutes while waiting for the Circle line.
