I will agree with you somewhat Josie. That’s why they call it a medical practice. They are constantly discovering new ways to do things. Could you image if you had kidney stones say 150 years ago. How about a tooth pulled? Yes, they have come a long way, but if I could come back say 500 years in the future, the first place I’d check out is a hospital. They have so much they don’t know about the human body. There are many inventions still to come I believe. Especially with the brain and central nervous system. It’s like the bottom of the ocean.
