Health Insurance: "Young Invincibles"

Here's a video from CNN about a young bike messenger in NYC who does not have health insurance. He says he's been in a few health-related binds on the job. See what you think. As mentioned previously, I advocate purchasing health insurance if it is not provided through your employer (some is better than none). Here are my thoughts on the bike messenger:

1) It may be possible for him to get a short-term policy for relatively cheap if he's healthy.
2) If you are a bike messenger is it difficult to obtain medical coverage? (It seems like a high risk job...)
3) Does he have a medical condition that prevents him from obtaining affordable coverage?
