Here’s the sneaky twist: the clock runs faster when it’s hot. If it’s a scorching 90°F summer day, your safe window shrinks to just one hour. Your car counts as an oven. A sunny picnic table counts as a sauna.
Conversely, a chilly 40°F day might buy you a few extra minutes. But let’s not get clever. Unless you’re eating your sandwich in a refrigerator, don’t push it.
The danger zone is the enemy. Between 40°F and 140°F, you’re playing Russian roulette with your digestive system. Fun for the imagination, awful for the stomach.
