Well that is the most important thing. Smoking kills. But if you are shopping for a new windpipe nanotechnology has the answer. Doctors at University College London have developed a synthetic nanometer-scale material that can be fashioned into a windpipe. Not to be content with making another piece of synthetic tubing, it was transplanted into a patient in Sweden. First doctors took a 3D scans of the patient’s windpipe and used that to create a new artificial one. The nanomaterial was designed to attract cells that were taken from the patient’s bone marrow. Then the whole thing was reinserted into back into the patient. As of about a month ago the patient was doing well returning to his home country of Eritrea. To be honest I don’t know what the cause of his cancer was, but still do not smoke.
