Dont quit your day job until you can afford it if it is important to you.
When I was in my late 20s I didnt bother with it. After my daughter was born and I got in to my mid 30s I signed up for it. So far in the last 7 yrs Ive had appendix out and back surgery so thats about $30k worth of work insurance paid for.
I wouldnt think about going without it at my age now if you value your credit rating as any one of us could be 1 day away from a several $100K hospital bill that would crush us financially. Thats my 2 cents.
