You can say that again, they used virtual reality to work inside my heart without cutting me open. It involved an MRI image taken the day before, radar antennas stuck to my chest and back (no, really, there were four of them) and two "imaging techs" that ran the equipment while the doctor did the work. Eleven holes in my body but no incision at all.

And cancer treatment is just as hi-tech. I've lost count how many around me have been thru cancer and are doing fine.
