Someone said that if a person is deceived once, it's the deceiver's fault. If the person is, however, deceived a second time, it's on the person.
You can bring a camel to a water source but you sure can't make it drink from it.
I have another five popular proverbs about this but I don't care anymore.
We might not know what long term exposure to Ti will bring on us but why content with anything lower than grade 1?
Heck, those guys using titanium nails (I have no idea for what but they call it "recreational activities") have all switched from grade 2 to grade 1 years ago because of TiO2 formation and some of us are trying to go the opposite way in vaping?
