A new story on how they've discovered the gene responsible for a genetic pre-disposition to diabetes (and all you ever hear is it's because people eat too many carbs... wrong - even before the gene was found it was known to be a genetic problem.)

Apparently according to this article the the gene in question is #10.... you might have one copy that's bad or two but having even one increases your risk of Type 2 diabetes significantly. As for me - well I already have Type 2 Diabetes so no reason for me to get tested - and as for my son - why would I possibly want to have him tested? I don't plan on telling him I have Diabetes once he's old enough to really understand because I don't want him to be black-listed for insurance and other activities - thus what possible benefit would there be to getting him tested? The fact is leading a healthy lifestyle with exercise and diet is the only defense until and after you get diagnosed so unlike say a breast cancer risk where you might choose surgery to remove the risk, the test really doesn't provide any value.
