Well, checkups are expensive...
A $100 checkup* is insignificant when compared to million-dollars-worth health.
(P.S.: I dunno how much checkups in the US cost; the $100 thing is something I'm assuming based on what I saw on TV as a kid; as for the "millions-worth-health", that's something my Grandpa used to tell me.)
EDIT: People, I need a bit of clarification here. The more I seem to learn about the USA the more I find it stranger and crazy, sometimes quite awesome (making me wish I lived there) and sometimes devoid of any plausible sense (often making me happier for where I am). In either case, I always seek to confirm the information I here elsewhere because I don't take any information for granted, so I hope you forgive my curiosity.
If a child is bullied at schools and is seen developing strange changes in behaviour, is that the first thing a lot of parents do is put the children on depression medications? I hope someone can correct me if I'm wrong.
