HMO vs PPO

In case, you come across this stuff. You know, the highly debated American health care system. No, it's just a difference between HMO and PPO. You don't know what it is? Go wiki it. I know it's kinda long winded, but it gives you at least some idea on the health care insurance type.

Quote from my friend: these stuffs are extremely low yield. No need to spend too much time on this stuffs? Sounds rational to me...
