Ya know why young people don't have health insurance?
Because most young adults don't need it. But then they get married, they start thinking about having kids, and they realize that their kids need health care. And they get established in adult jobs, which generally have some kind of insurance provision. And they start paying into those flexible healthcare spending accounts.
Young adults aren't "adopting an attitude that their youth protects them." In the vast majority of cases, their youth actually does protect them.
Honestly, until I was 24 (and married, and pregnant, and both of us employed) I could handle just about everything that came my way with aspirin and a can of chicken soup. And if I hadn't been pregnant, I wouldn't have noticed our medical coverage, even then.
In fact, I don't really remember needing to see a doctor for my OWN health for anything other than an annual girly exam until I was about 29.
And Hubby, well, aside from the occasional stitch, that freakish bout of the mumps, and the time he scalded his throat so bad he couldn't swallow, he didn't need a doctor until he broke his leg (spectacularly, I might add) at 42.
Granted, I am one of those annoyingly clean-living people. If I were a heavy drinker or a smoker or a drug user or liked risky sports, I guess I would have been in the doc's office more.
But, hey, that's why if you don't have health insurance, you better do whatever you can to protect your health...and find a job with benefits. The universe rewards those willing to plan a bit.
