My mother’s uncle used to tell me, “I’ve had my arms soaked with DDT spray (diluted in water), and I’m still here!”
He told me that when he was 87. He lived to 88, but had tripped backwards getting off his lawnmower, hitting his head and dying from brain damage.
In all my years of farming with livestock, the cattle oiler (that they would rub against) and the summertime corralling and spraying the herd with approved pesticides, worked quite well...
And,... pour on ivermectin.
“tripped backwards getting off his lawnmower”
At least he died doing what he loved.
