How many blacks are arrested and convicted while being innocent? This systemic racism is why these numbers can't be correct nor relevant. Note the source of the stats, I think Asians just hate black people.
I grow in a furnace room with a hot water heater. The only issue I believe I've had was some negative room pressure causing exhaust to enter the room from the hot water heater flue. I avoid that now by monitoring the total CFMs out vs. the CFMs "in." I'm still here after 15 years in that room.
