  • 07:34:28: Awake. Stayed up too late, so...wishing for more sleep. Alas, not happening until tonight...too much to do again.
  • 07:35:48: OTOH, the last 700 words of writing, all post-midnight, accomplished something important. Now for the next 8000. Or so.
  • 13:27:40: Today is "cut down the rotting/leaning tree" day. And "prune the live oaks" day. The song of the chain saw snarls across the land.
  • 15:54:59: Our barn cat Cleo was attacked this morning by a larger cat and lost some fur--I levitated out the door, chased the baddie away....
  • 15:57:03: ...checked the damage--less than expected, thanks to very heavy undercoat, some now missing. Long petting session in afternoon.

While peeling apples last night, I was reminded how little force it takes to penetrate skin with a really sharp blade (cooks develop callused thumbs, and this is a good thing...no blood on the apples, just a sting.)   A friend in the SCA told me about research done to determine if someone could "accidentally" stab someone else, and the answer is a definite "Yes."    Human reflexes are too slow to pull a knife point back if either the knife-holder's arm is moving forward, or the other person is, when the first contact is made...because to a sharp point, human skin is hardly a barrier.  

The edge of a really sharp knife is just as efficient at parting skin (or lopping off fingernails...I can't count the number of times I've left my thumb that tiny distance too close to a chef's knife and removed part of my left thumbnail, sometimes including a bit more than thumbnail.  A somewhat duller knife will also do it--which is why dull kitchen knives are more dangerous than sharp ones; they can "skip" on a tough bit of what you're cutting and leap onto a finger...and again, reflexes are too slow to reverse the move.
