I've had half a dozen major surgeries and spent nearly 2 days on life support in 1994. I probably died for a minute or so more than once. Thanks to skilled surgery and anaesthesia teams, I came back.
I learned from Dr. Knuth that you can put a tombstone on something, without burying it, and save yourself the hassle. It's very effective! Especially if you're just going to plow that area and move all the live ones eventually anyway.
