I prefer to live dangerouslyyou dont need it unless you are going to have a medial problem, so predict the future before you go then you'll know what to expect. if you cant predict the future then you'll need to get insurance or take a risk. the risk is far greater than the cost of insurance, so you will need to have parts of your brain missing to take that risk.
I just save up all my illnesses until Christmas when I come home ... lol
