Rust consumes iron and envy consumes itself

I wonder what some of the dark spots are....



In my worst scenario, this airplane is stained because it's a big piece of junk. There's more rust than clean metal and therefore the plane will crash within 5 seconds after take off. All 9.000.000 passengers and all 5.000 members of the crew will die, on the spot or in the hospital, and I survived because my car broke down and the only place they could get the spare part was China.
When teeth are stained, this can have many causes, e.g.
- aging
- food and drinks such as tea, coffee, red wine and blackcurrant
- smoking
- calculus or tartar
- antibiotics

Unlike (in my mind)/just like (in real life) airplanes, in general, teeth will not 'crash' just because of some stains. A proper teeth whitening can solve the problem. Not for ever, but for quite a long time if you practice good hygiene and avoid most of the above.
