Not that he didn't fundamentally understand the words and why they would worry the average American male of a certain age, he didn't stay that far away from the biology labs and he did have a little, so subtle, hardly anyone knew about it, history of heart problems, but it felt to Tony like Bruce was ten steps behind and that couldn't be right, Bruce was the smartest person Tony knew. "You feel strongly that our lifestyle has a high risk of heart disease brought on by poor diet. Not the stress or the 900:1 on being wished out of existence by an advanced alien species well before the blood pressure becomes a major issue. It's the hamburgers." Just so they were clear.
