Type I is being genetically unlucky with a genetic disorder that attacks one's own Beta cells, it's very unfortunate. Hopefully the attacking cells can be withdrawn or more signifcantly stems cell can regrow Beta cells in an pancreas. What is worse about type II is that it is slow. It is a biological resistance, it takes years to come on. It's not a genetic fault one day, it is the consistent and unrelenting attack on one's body. Of course it is crippled eventually when you pump sewage through it daily. The best thing we can hope is that obesity related diseases become more fatal as time goes on so we do not need to pay for their healthcare costs as they slowing die from the inside out.
