If you are a female:
Start out by imagining yourself as a boy.
Then, imagine yourself as a boy who is imagining himself as a girl.
Then, imagine yourself as a boy who is imagining himself as a girl who is imaging herself as a boy.
(If you are a male, please reverse the genders in this thought experiment and proceed. You get the drift.)
I can go only two layers deep, at least for now. How about you?
A team of investigators developed the silk plates which can be absorbed by the body over period of time.
The researchers, from Tufts University, found that metal devices pose an increased risk of infection and poor wound healing.They can also be stiff, causing stress to the bone structure.
Silk-based sponges, ﬁbres, foams, have been previously developed for use in the operating room but silk has not before been used in the development of a solid medical device.
To test the devices, pure silk protein was obtained from silkworm cocoons to form the surgical plates and screws."
