With arthritis in my fingers (too), a warm wrench is SO much nicer to grab than a cold one. Kind of the opposite of when working outside in SoCal and having to wear gloves because the tools got so damn hot in the sun.
Last spring I was forced to endure the air in Phoenix one night. Needless to say, there's A/C in my friend's house, which made the usual noises. Yes, I slept (sort of) but that was thanks to having been up for about 20 hours and then drink quite a bit.
