I've been on this life support treatment for 5 years now, it's called dialysis. I have to do it 3x a week to clean my blood from toxins because both of my kidneys are dead. It still amazes me how my blood leaves my body and goes to this machine and gets cleaned and then flows back to my body. It happens for four hours every session. Such a great wonder of science that I am so much grateful for. It has extended my life for 5 years. Without it, I could have been gone.
