OK, perhaps many of the readers have heard rumblings about radical life extension technologies coming along in the decades ahead from many scientists. One possibility is taking some of the patient's cells, multiplying them, then using those cells to 3D bioprint out organs and tissues. The organs and tissues would then be put into the patient's body as replacements for old, worn out or diseased organs and tissues. The idea is to replace your organs and tissues every so many years with new and healthier organ and tissues, such that a person's healthspan and lifespan are greatly increased, perhaps even increased to centuries or millenia of life. If a sampling of a patient's cells are frozen when the patient is twenty or thirty years old, then thawed out and used for 3D printing thirty or fourty years later when the patient is fifty to seventy years old, then those cells would still be fairly youthful, in part because the telomeres on their DNA would be much longer and partly because of other factors. Youthful cells produce youthful tissues and organs. It would be like having a twenty year old version of your lungs put into your body as a replacement. 3D Bioprinting will develop over the next thirty years or so to the point where we will be able to print out functional organs. But if a patient does not freeze some of his or her cells in their twenties or thirties and instead waits until his sixties or seventies to freeze them, then the cells used for 3D bioprinting would be much older and prone to illness. Thus the new organs would not be as effective and the patient might not live to as long a life as radical life extension offers. DE
