Special chairs have been installed at subway stations to accommodate obese passengers in Brazil.  The seats are blue, nearly twice as wide as normal chairs, and can support up to 550 pounds without breaking.  That sounds really subtle.  Apparently obese passengers aren’t using them because it’s too embarrassing.  I guess if you’re 550 pounds, just use the stupid thing. It’s not like we can’t see you, and it’s not like you can pull off “No big deal, I’m just going to stand.”  Can you imagine that awkward moment of standing next to the person that should be using it, and that’s the only seat left?  “No, really, you take it.  You look like you should sit down before you go into cardiac arrest.”  Or “Hey…take that seat.  By the way, I loved you on Cheers.”
