The Perception of Time and Energy

You don't see in real time. Your brain is always about a tenth of a second behind,

so everything you're watching right now is technically the past. Your brain just

edits it together seamlessly so you never notice the delay. And here's another

mind bender. Time feels faster as you get older because each year becomes a smaller

percentage of your total life. That's exactly why summers felt endless when you were eight

but now entire months just vanish. Your brain also burns twenty percent of your body's total

energy even when you're doing absolutely nothing. Thinking is literally exhausting you.
