If you ask me, there are any number of physically possible solutions for each one of all the six problems that were pointed out in the attached article…
If you ask me:
*Problem 1 which is locating organs in the body under micro g conditions, can be fixed with 3d body scanning technology.
*Problem 2 can be solved by employing elastic bands throughout the day
*Problem 3 can be solved by using actuators to shove the body upwards at 1g to 2g for a short distance, so that the fluid goes with the momentum, then lowering it slowly.
*Problem 4 can be solved by placing subjects feet in an automated container so that a machine can remove the subjects socks and wash the subjects feet
*Problem 5 All that you have to do is let a machine clean the laceration and press it together with machine precision then glue the laceration together or use a sewing machine do the stitching or apply butterfly stitches
*Problem 6 Apply suction to the toilet drain and a blower to the top.
