endless iterations

I was just fake-lecturing. I don't even know if my deodorant has aluminum, I smoke, eat meat, drive a truck, and I'm okay with fur from meat animals. Simon & Garfunkel are pretty good, though.

However, aluminum is probably bad for you.

Wikipedia says:

Aluminum has been established as a neurotoxin.[14] Aluminum chloride, an aluminum salt that is commonly used in antiperspirants, is also commonly used in studies on aluminum-induced neurotoxicity.[15][16][17][18][19] Aluminum itself adversely affects the blood-brain barrier, is capable of causing DNA damage, and has adverse epigenetic effects.
