Men with knives... will they always be necessary?
I'm not thinking about alien assassins, aliens with table manners, or futuristic barbaric warriors. I'm thinking surgery.
Assuming for a moment that wars are not fought by champions playing chess, or out-singing each other, or displaying their terrifyingly impressive tails (or other body parts). Someone is going to get hurt.
I do "buy" heroines who can "do" pyschic healing.
In fact, the 2006 Romantic Times Conference, Pyschic Sunday was a real mind-opener. Two psychic healers --one hands-on, the other hands-off-- helped an unfortunate person with a visibly swollen face and abcessed tooth, and also on a number of others.
The psychic healing was very responsible, the point was made that all methods are complementary and the sufferers were also told to see a conventional doctor. However, whatever they did seemed to work.
I like medicine based on plants and other natural substances, too.
I have trouble suspending disbelief when a mortally injured party is put into a futuristic light box (like a seed propagator? like a tanning bed?) and they recover "just like that" --to quote the memorable, Fez-wearing magician, Tommy Cooper.
Maybe I accept it for some ailments. Immersion in the sea is supposed to be restorative. It certainly does great things for my feet... unless I step on a weaver fish, of course, or get stung by a jellyfish. So, I can believe that being bathed in some sort of light might be as good for me as being bathed in some sort of liquid.
Should I infer that the light box is akin to teleportation as medicine. I should re-read The Physics of Star Trek (which is on my keeper shelf). Beam Me Up, Scotty, is fine. Beam Me Well?
Sometimes, just taking my rotating head electric fan apart and putting it back together again the way it was does work for a time, but it wouldn't if something was broken or rusted.
Lasers, I suppose, could replace knives. My problem is, when I think of lasers, I think of a couple of James Bond films... Goldfinger, Die Another Day... and I shudder at the thought of laser eye surgery. I know I shouldn't.
Do I think that a machine with a laser could replace a man --or a woman-- with a surgical knife? Yes, but I don't want to write about it, any more than I --personally-- want to write about an android with a libido.
Terminator with a tool? Great for action adventure, and I daresay he would have been very competent in the Operating Room. But for a fictional frisson, give me a masked man with a very sharp knife, every time.
