Ahahaha.
On topic, I've seen enough examples of those that could and couldn't handle significant events where both of them sweated the small stuff to not observe a direct correlation between them. While both are stressors, they target the person differently, and how/why they cope in the ways they do vary strongly.
For some, they sweat the small stuff and appear to handle larger problems from there being a perceptive threshold of sorts. When something is too much, other barriers kick in, but the stuff under that threshold can appear to strike harder from it being blocked out less. It's easier to allow ourselves to stress over that which doesn't matter than it is to face that which is harder to fathom.
When something is too much, blind spots and defense mechanisms can become much more apparent than when there's less worth defending against. Someone being five minutes late is far less of a problem than one's own mortality, and yet you may see such a person externally worrying more about the former than the latter despite how much the latter is eating at them in some way. In many cases, the general stress proxies onto other areas as an outlet for it where the actual problem doesn't need to be faced.
For myself, when things become too much, my OCD-like tendencies and other flawed areas increase exponentially even though those problems themselves are completely unrelated, while the real issues are barely on the surface of my mind.
