Reminds me in one of myriad Trump threads when I said his diet and lack of exercise on top of his age might do him in early. Sure, there is plenty of evidence that gallons of soda, buckets of KFC, Whoppers and Big Macs are some of the worst things you can put into your body, and lots of evidence that not exercising and being sedentary promotes poor cardiovascular health and increases the chances of heart disease, especially when you're 70-years-old. But, despite this evidence, I did not say it will do him in because it may not. Despite the evidence, there is no proof this will happen.
Sort of like how cigarette package warning labels say things like "may cause" or "increases the chances of" or "known to cause." Of course there is a great amount of evidence to suggest these things can happen, but there is no proof they will happen, even though every smoker out there has lungs full of tar.
