I hate the kind of chemo-phobia engendered by sites like this.

I'm a retired chemist, in his seventies, in good health. If chemicals
were this bad, I should have been long dead by now.

In fact, my graduate adviser, in his eighties, just got out of jail last
year after conviction 20 years ago of running a meth lab.

I'm fairly sure you did not work with the chemicals you were using in
the same unsafe manner that cookers do in a meth lab. You were probably in
a laboratory with soapstone horizontal surfaces and some sort of local
ventilation.
