Investigation:
In the medical field, we are truly living the future. The fear of dying is less felt in hospitals compared to being on a waiting list for a good-willed person to donate an organ versus the new scientifically grown organs engineered to act exactly as our natural organs. So far, there is artificial skin and cartilage, synthetic windpipes, artificial blood vessels, and bladders as well. The only problem is that in order for larger and more complex organs (like the heart, muscles, and tissues) to function perfectly is that they have to "feel" the environment. For example, grow and perform in the right blood ph, temperature, and cells and bacteria. Well, at least the common, artificial organs we have today are working perfectly, a bladder has already lasted for more than a decade on a past patient.
