Considering the vast number of us old guys still around that used all those bad things..
solder, acetone, diesel, glue... These things won't kill you. If they could, they're be a lot more flying time at the local field during the week when us old guys go..
Not to say that some precautions aren't good, but fear.. Naah.. that's just a reaction to some gummint idjit with an agenda pushing his favorite whipping thing because he and only he knows what's best for everyone else!
Like those idiot labels all over ladders.
Golly, ladders are the modern equivalent of the gene-pool cleansing Saber Tooth Tiger! Go pet the nice kitty, and fail to contribute to the gene pool. Stand on the top of a ladder, and fail.... That's nature's way!
