The "good" and "bad" labels feel oppositely placed. Maybe because I associate "good" with positive values and "bad" with negative values. But I haven't made a linear graph since high school, so take my comment with as much salt as you care to.

Leaded gasoline didn't sound like a good idea to the general public when it was invented. Its inventor had to do dumb stunts in front of crowds to get people to accept it. Turns out, he was wrong. He was also wrong about CFCs. Though at the time, they did generally seem better than ammonia.

yeah I've heard that Fecal Transplants can change a person's life. gut microbiomes really affect a LOT about us. the only thing is trying to get it to work without issue. placing part of a healthy person's microbiome into an unhealthy person's might not work for that person or worsen their problems
