I was just reading this article about a mathematical understanding of closed time-like curves.
In essence, the argument is that time travel to the past is possible with a degree of free will, but you would not be allowed to alter the past in such a way as to remove the motivation for traveling back in time. E.g., it would be like Futurama where Fry kills his grandfather, but he impregnates his grandmother, thus allowing himself to be born. The idea is that the timeline would correct itself and ensure that your future self will always return to the past.
There’s no need to be fair here. Insulin is absolutely essential for diabetics, and the head of the FDA trying to proclaim that cooking classes are a viable alternative is nonsense. For type 1 diabetics, no amount of healthy eating is going to get their body to produce insulin. For type 2 diabetics, it is possible to eventually get to a point where you can be stable without insulin, but not for everybody and not right away. Insulin treatment is the only way to survive with diabetes for an extended period of time, and the focus needs to be on ensuring that insulin is both affordable and accessible.
Yes, there are things to improve in our food supply, but don’t let that distract from how egregiously insane his comments are about diabetes.
