1. After our society removed lead from petrol (gas), I thought the herd would get smarter. It seems the opposite is true.
   Bring back lead in fuel, tongue firmly pressed into my cheek 😉

2. If you ever want to try out lead free, try K100LD. It flows like 60/40, just hotter

3. I use 60/40 and don't really care about poisoning since I don't put it in my mouth 🙂
   Have worked as a typecaster, dealing with an alloy of lead, tin and antimony, most of it being the lead. Not worrying about the vapours too much though, as the metal is close to its melting point and the intermolecular bonds will keep it from evaporating. Haven't even smelled it.
   The real deal is volatile organic components from decomposing machine oil on typecasting machines, or flux from the iron tip. That stuff can be cancerous if you inhale too much of it.

   Smelled enough acetone, isopropyl alcohol, ammonia, toluene, cyclohexane etc. through my studies in chemical engineering. And I think I'm still rather smart, LOL.

   Asbestos… yes, I remember your commentary on all these girls working in the vacuum tube manufacturing industry.
   As long as it doesn't strip off forming fibres, it's relatively safe. I wonder if asbestos could be kept together with some spray paint that forms a rather thick and flexible layer, and penetrates the pores in the stuff.

   "Mercury, lead, asbestos" is good, but "salt, asbestos, curtain" is certainly better 🙂

4. I get tested about every two years. I'm on year 38 of soldering. A lot. So far I'm below detectable limits. Always wash hands afterwards! Don't eat or drink at the bench.
