Cold Hands Cure Attempt, an Update

A few quick words on the "cold hands cure" I've been attempting for a wee while now.

• Doing it every day gives the hands a really hard time. I've backed off a lot.
• There does seem to be something to it. Scotland is in the grip of a cold snap at the moment, but my hands aren't cold to the point of uselessness doing outdoor work  - I was cleaning and lubing rear brake calipers and handbrake cables for about 45 minutes on the weekend, with some discomfort but no reduction in grip strength.
• On returning indoors from the outdoors, I get a rosy feeling within my hands, something I can't say I've felt before.

Strange, n'est pas?
