The colder wateveritable the capillaries, so if you do nick yourself, if it's small enough you'll not know about it until you apply some aftershave, if it is a bit of a bleeder, the splash of cold water to rinse off helps shut it down. If you really screw up you'll need the styptic...Or possibly a paramedic...Depending on the level of stupidity involved I suppose .
I cold water shave all the time...But I'm also lazy, so that might have something to do with it.

Was thinking earlier that you are a veritable encyclopedia, now you are just confirming it. I am not even being a cheeky young scamp or anything. Now it sounds like I am, but I am not, pass the bailing twine and sticks.
