When I was in college, I couldn't afford health insurance (no parents + financial aid does not cover it). I played rugby (generally not the safest sport) for two years, in addition to playing pickup basketball all four years. I very fortunately did not sustain any major injuries.
Six months after graduating (and getting a job with health insurance), I tore my ACL while playing pickup basketball. The costs were as insane as outlined in this post, but, again, I had health insurance. However, to this day, I'm horrified at the thought of what would've happened if I'd sustained the injury in college when I didn't have health insurance. Shame on me for putting myself in those sorts of situations, but it feels like there's something wrong when the penalty is so harsh.
