why don't metals smell?

(and please don't say because they don't have noses...)

Good personal hygiene?

Actually, it's because metals don't (generally) give off particles.  When you smell anything - bacon, coffee, candles, your pits - it's because little bits of whatever-it-is are getting in your nose and giving the olfactory receptors something to do. But you CAN smell metallic compounds, like iron oxide. Why?  Because the compounds are in a state that gives off particles.

I got a good whiff of iron fumes today while cutting up a bunch of tubing for a frame I'm making to mount up the new fence to my table saw. Lots of shiny specks on the driveway that I was sure to sweep up so that they don't get tracked into the house and ground into the wood floors. I'll have to put up some sort of protective baffle so that when I'm arc-welding it all together tomorrow or the next day I don't blind the neighbors. I have enough tube "left" to make a nice table for copper working.

It's not really random if I try to come up with something random.

But always plan on spontaneity.

All cosmologists are racists!

Why can't they just refer to it as African American matter and energy.

If a black guy shoots a white cop, can he use the defence "he was armed and I was afraid for my life?"

Question also applies to a white cop shooting a black cop?

If you see an amputee being hanged, is it wrong to start calling out letters?

If Pluto isn't a planet because it's too small, then are midgets really people?
