Yeah. Someone else suggested it might cover your first ambulance ride. I'm thinking maybe your first year health insurance?
Edit - it was just a wild guess, but here's a badly formatted table copied from an article in Forbes:
Age of member Average monthly costs
- Age 21 $445
- Age 27 $467
- Age 30 $505
- Age 40 $569
- Age 50 $795
- Age 60 $1,208
So, for my age, my guess was almost exactly right!
