I'm reading Richard Bernstein MD "THE DIABETES DIET" since I have Insulin Resistance/Metabolic Syndrome and learning so much . He has lectures on YouTube that are worth listening to since he has Type 1 Diabetes. He got it at age 12 and is 78 now, although he was only expected to live to age 42 back then.
He has a quote like yours in that he believes in the "LAW OF SMALL NUMBERS". He says you can manage anything in a small amount but as you double it, it grows exponentially.
