Space travel makes mice run in circles. NASA once sent 20 rodents to the International Space Station to see how the effects of space affected mice. Not long after they got there, the mice all started running in loops inside their cages. No one is exactly sure why this occurred, but researchers stated that the critters might’ve just been enjoying their time in space.
100 Mind-Blowing Enjoying Facts
Individual people can experience time differently, too. You’ve probably noticed how time seems to speed up when you’re racing against a deadline or having fun, and how it tends to drag when you’re bored. This is because when you’re focused on something, like a big work project or a party, your brain pays less attention to how time passes. But when you’re bored, or your brain is less stimulated, you become more aware of the passing of time, making it feel slower. One study proposed that dopamine—the neurotransmitter and hormone that helps us feel happy—may be an additional culprit. It showed that increased dopamine production, which happens when you’re enjoying something, may slow down your body’s internal clock, making time feel like it’s flying by.
