At a spa–carnivorous plant farm in northern Israel, you can get a snake massage for just $80. Spa mistress Ada Barak came up with the idea after visitors who came to scope out her carnivorous plants (which eat schnitzel, among other things) enjoyed the sensation of holding the garden snakes she’d pass around after the tour. For the snake massage, she basically plops a mass of entwined snakes of various sizes on your stomach and lets them slither all over you. This is supposed to have “calming and curative effects.” Time sent a writer to try out this treatment. “After some experimenting” Barak perfected her treatment with a combination of big snakes which produce a kneading sensation and little snakes “whose passage over the skin is a trembling flutter.” How big is big?
Just as I am psyching myself up for the treatment, I see one of the little snakes, with a string of brick-colored diamonds along its spine, open its mouth impossibly wide. Is it going to strike? No — it coughs up a half-digested mouse, leading me to assume that the snake is as queasy about giving me a massage as I am about getting one.
Wow, gross? To top that off, once the snakes get to work, one nibbles on the subject’s eyelashes. The writer emerges from the “massage” feeling “relaxed and curiously lightheaded.” You know, if snakes that ate mice had a nibble of our eyelashes from the comfort of our stomach, we’d feel a little lightheaded, too.

Amputees can feel relief from phantom limb pain just by watching someone else performing “virtual” massage. The treatment appears to fool the brain that it is their missing hand being massaged, California researchers say.
New Scientist magazine reports that it harnesses nerve cells in the brain which become active when watching someone else carry out an action. UK experts said this kind of therapy may help amputees, as long as they can go along with the illusion. Mirror neurons in the brain fire up when a person performs an intentional action, such as waving, and also when they observe someone else performing the same action.
They are thought to help predict the intentions of others by simulating the action in the mind. Similar cells exist for touch, and become active both when a person is being touched and when they watch someone else being touched.
Researchers at the University of California, San Diego, say the reason people do not constantly feel what they observe happening to others is that a person’s sensory cells do not give the right signals, so they know it is not happening to them.
In the study, Vilayanur Ramachandran tested the therapy on ex-soldiers. His first test used a device called a mirror box, which he developed. An amputee puts their remaining limb, in this case their hand, in front of the mirror and their brain is tricked into thinking the mirror image is actually another working limb.
Two amputees had their normal hand touched while using the mirror box, and felt the sensation of being touched on their missing hand. In a second experiment, when amputees watched a volunteer’s hand being stroked, they also began to experience a stroking sensation arising from their missing limb. One even said their pain disappeared for between 10 and 15 minutes.
Dr Ramachandran suggested the amputees “felt” the actions of others because their missing limb provided no feedback to prevent their mirror neurons being stimulated, and therefore not telling them they were not “literally” being touched. “If an amputee experiences pain in their missing limb, they could watch a friend or partner rub their hand to get rid of it.” But Dr Ramachandran said there could be other uses for the therapy, including helping people who have had strokes. “If performed early enough, it may also be used to help stroke patients regain movements by watching others perform their lost actions.”
Kate McIver, of the Pain Research Institute at Liverpool University, said work done there on helping amputees create mental images of pain-free limbs – which operated on the same basic principle as the US research – had also proved effective. She said watching massage could help, but added: “With something external like this, the patient has to accept that the illusion is real for it to work.”
